I thought you had requested in which 1.7.10s snapshot it broke.
So the earliest snapshot I could find for 1.7.10s does have the problem.
It works in 1.7.9.

As I mentioned earlier in cygwin-inst-20120415.tar.bz2, a 1.7.11s
snapshot it's fixed. That's the snapshot that was current when
it was suggested I try the latest snapshot.

So, you must be wanting me to check the 1.7.11s snapshots to see
if it's fixed in an earlier 1.7.11s snapshot.

I'll have to check that out next week when I should have more time.

That is because a subprocess which still has an an open pty associated
with it maintains a connection to the originator of the pty.  setsid
breaks that connection.

I had a little bit of time this afternoon to start on the snapshots
prior to 20120220.  I had enough time to try several of these instead
of the first 1.7.10s snapshot I reported on.  Since it is necessary
to stop any and all cygwin processes before switching the cygwin1.dll's
each time I try a snapsnot, I ended up going through several iterations
where I remembered to stop everything started by cygrunsrv at startup,
but forgot on occasion to stop gpg-agent.  Interestingly, the problem
occurs when I have not stopped gpg-agent.  It turns out that I built
gpg2 on cygwin with the resulting gpg-agent at the same time I had
upgraded to 1.7.15.  So this problem with 1.7.15 and later is because
exiting mintty does not stop the gpg-agent that is somehow associated
with it and according to an earlier post in this thread, unless
a process associated with mintty is started with setsid, if it
is still running you could have a problem like this.

I haven't looked to see how the gpg-agent really gets started when
I fire up mintty, but with gpg2 configured to use gpg-agent, it does.
So, if I stop gpg-agent in ~/.logout under tcsh in mintty, the problem
with 1.7.15 and later disappears.

This is NOT the problem I first reported some months back.  That got
fixed with cygwin-inst-20120220.tar.bz2.  I was not using gpg-agent or
gpg2 prior to 1.7.15 and just happened to do the 1.7.15 upgrade the same
day I installed gpg2 and when I logged off windows got the problem
with Windows wanting to end mintty even when it had been properly
terminated ever since.

So thanks for everyone's patience in what turned out to be a red-herring.

That's not very helpful, unfortunately.  You reported in Feb or Mar that
one of the snapshots fixed the problem for you.  And you reported that
it's now in May broken again.  So there's one snapshot in the list which
was the first one which fixed it, and there's another snapshot in the
list which is the first one which broke it again.  If we know which
snapshots that are, we're a big step further to fix this problem again.

Today I had a just enought time to try the first 1.7.10s snapshot I
could find on the cygwin snapshots webpage.  That was
cygwin-inst-20111217.tar.bz2, and the problem does exist with that snapshot.
I don't know if there were any earlier ones prior to that but
after 1.7.9 or not since the chart on the webpage starts with
that snapshot.

This will take a little time since one has to log off to see the problem
and I have no idea which 1.7.10s was the starting point.  Unfortunately,
the rest of this week, I won't have very much time to do many
iterations.  I'll see if I can find where it started and post back,
but unless it's in the first few tries, it will likely be sometime
next week before I have the answer...

That's why I'm asking.  If you could try to find out which snapshot
fixed it and which snapshot broke it again, it would help to find the
cause.

This is with Windows XP SP3.  I am in the administrator group, but I
don't invoke mintty as administrator, only as I normally run as me,
but I am in the administrator group.

It's not impossible that is bloda, but it is odd that it comes and goes
with various cygwin releases then.  It clearly started when I upgraded
to 1.7.10, and clearly disappeared with the 1.7.11s snapshot and then
clearly appeared again with 1.7.15.

This problem first appeared in 1.7.10.  The snapshot I downloaded
that fixed it was "cygwin-inst-20120415.tar.bz2" that I downloaded
on April 17, 2012.  The first go around of posts on this went
without replies for quite some time after 1.7.10 came out.
After one of my posts that questioned whether there were
very many seeing this problem, someone posted that I should
try the latest snapshot, so there is a chance the problem
was fixed in a snapshot previously to the one I downloaded.
The one I downloaded was current as of the day the post appeared
suggesting a snapshot, so it could have been where the fix was.
Nonetheless I responded to that post with a post saying that
that snapshot fixed the problem.  There were no further
posts on the subject until now.

If the code in question has changed a lot, it's only marginally helpful
to refer to a change in older code.  OTOH, knowing both, which snapshot
"fixed" it and which snapshot broke it again could be valuable.

Perhaps figuring out which snapshot between 1.7.10 and 1.7.11 fixed it 
would be faster? It sounds like he didn't go very long between 10 and 
[some] 11s. Not sure it would be as enlightening, though, especially if 
it's one of these cases where some undefined behavior just happens to do 
less-horrible things than usual for some reason...

Can you try to find out which snapshot introduced the problem?

That's about what I figured, which is why I'd never worried before. 
Although I will say I've sometimes had trouble figuring out what cygwin 
process might be keeping the mintty alive...

Yes, your understanding is correct.  My bloda spectrum hasn't
changed since 1.7.10 and is pretty well in hand.  When the problem first
appeared in 1.7.10 and I posted about it, a few days later I got a
suggestion to try the latest 1.7.11s snapshot and see if that fixed it.
 It did, I haven't had the problem since until 1.7.15 and 1.7.16s.

This isn't a show stopper, especially since in this incantation it
doesn't happen all the time, however something isn't quite right...
Interesting the Cygwin X apps aggravate the problem.

Do I understand you correctly that you no longer have any mintty
windows open when this happens? That's puzzling indeed. Have you
looked at ye olde Big List Of Dodgy Applications?

Mintty closes when it gets an EOF from the underlying pseudo terminal
device. This happens when there are no more processes connected to it.
The Cygwin console behaves similarly, but other terminal emulators do
not: they close once the direct child process exits no matter whether
other processes are still connected.

Backgrounding a process with '&' or nohupping it doesn't break that
connection, but invoking it through the 'setsid' utility from the
util-linux package does.

There is never an "X" to deal with here.  One never know there is
a problem until he does start->Log Off to log out of windows.

I can normally close any/all mintty windows and then with various
process explorers try to find a mintty process and never find any.
Then when I log out of Windows, Windows claims it has to close
mintty.exe.  This was fixed once in a snapshot of 1.7.10, but
has since returned with 1.7.15.  In this incarnation it seems to
occur whenever I've run a Cygwin X app from a mintty window.
If I've signed on in Windows and never run a Cygwin X app it
generally doesn't happen, but I can't be sure it never happens.
Every time I've run a Cygwin X app though I can expect to see
it after closing (apparently normally) all mintty windows and
then log off of Windows.

I routinely encounter mintty windows that don't close after I exit the 
login shell they run (even though they contain no visible child 
processes), but they can still be closed using the big red "X" in the 
corner... your problem sounds like something more sinister.

It seems this happens at least when I try to log off after I've run a
cygwin X application from mintty, whereas with 1.7.10 it happened
all the time.

I'm puzzled why others aren't seeing this or aren't reporting it,
but this problem seems to be back with 1.7.15 and I've now tried
the latest snapshot (May 25) and it's back there too. It occurred
with 1.7.10 and then got fixed, but now it seems to be back.
