            Bug ID: 15650
           Summary: xemacs gdb cleanups.c:264: internal-error:
                    restore_my_cleanups: Assertion '*pmy_chain ==
                    SENTINEL_CLEANUP' failed
           Product: gdb
           Version: 7.6
            Status: NEW
          Severity: critical
          Priority: P2

>From my StackOverflow post:

http://stackoverflow.com/questions/17052457/xemacs-gdb-cleanups-c264-internal-error-restore-my-cleanups-assertion-pmy

I tried running GDB, version 7.6.50.20130508-cvs (cygwin-special), on Xemacs
version 21.4.21 but I get the following error:

/netrel/src/gdb-7.6.50-2/gdb/cleanups.c:264: internal-error:
restore_my_cleanups: Assertion '*pmy_chain == SENTINEL_CLEANUP' failed
A problem internal to GDB has been detected,
further debugging may prove unreliable 
GDB by itself works fine on Cygwin. On the Cygwin terminal, I did:

g++ -g -o HelloWorld HelloWorld.cpp 
to get the executable, and wrote

gdb HelloWorld.exe 
and then

r
and it worked perfectly. I then did

gdb -v
and the version turned out to be the same as the gdb used by xemacs, so it
seems that the error must be related to the interaction of gdb and xemacs,
instead of it being a gdb problem?

I found that some people had the same, or similar, issue:

http://old.nabble.com/-RFA--dangling-cleanup-in-find_frame_funname-td35521450.html

Any ideas? Thanks in advance!

The thing that would be most helpful is a stack trace of gdb at the
point of failure.

This sort of bug is generally easy to fix once its location is known.

Hey Tom,

How can I get a stack trace of gdb in xemacs?


Thanks,

What I would do is wait for the crash, then attach another gdb to the
crashing gdb using the "attach" command.  Then "bt".
Alternatively a core dump would work just as well.

gdb in xemacs after the error asked me if I wanted to create a core file:
"Create a core file of GDB? (y or n)"

I typed "y" and pressed "Enter"

And then it said Inferior GDB exited abnormally with code 1.

I then found gdb.exe.stackdump and here's what it said:

Stack trace:
Frame     Function  Args



That's it...

core file probably does not work in the cygwin environment well.
Therefore try to attach new GDB to the crashed GDB at the moment it is asking
"Create a core file..." and type "by" in the new GDB then.

OK I tried something new:

>From cygwin terminal, I ran xemacs as a background process via "xemacs &"
which gave me the PID 6040.

Then I ran gdb in xemacs and got the error. At the time it's asking me to
"Create a core file?..."  I went back to the terminal and did "gdb" -> "attach
6040" -> "bt" and got:

#0  0x774d000d in ntdll!DbgBreakPoint ()
   from /cygdrive/c/Windows/SysWOW64/ntdll.dll

Does this help?

--- Comment #8 from Jan Kratochvil <jan.kratochvil at redhat dot com> ---
I guess GDB had different PID than 6040.  6040 was for xemacs, not for GDB.

But I do not know anything about MS-Windows and how GDB behaves there.
It had some problems unwinding MS-Windows system libraries (which do not use
DWARF) but that should be fixed in gdb 7.6.

That's definitely not the PID you want.  Also, "bt" after attach will not show
the thread we need (Windows injects a thread in the process to stop it; that's
where that DbgBreakPoint comes from.)

Run gdb in xemacs until you get the error.  At the time it's asking you to
"Create a core file?...", look for the running _gdb_'s PID.  It's GDB you want
to attach to, not xemacs.  E.g., "ps -ef | grep gdb" in the cygwin shell may
work.  Then do "gdb -p PID" -> "thread apply all bt".

First of all, thanks for all the help, Folks!

So I called Xemacs from Cygwin Terminal and ran gdb in Xemacs.

Then I did the following...

Yes. Running gdb in xemacs *automatically* causes the "Assertion '*pmy_chain ==
SENTINEL_CLEANUP' failed" error.

Another possibility is to start gdb in the shell using the same
arguments that XEmacs passes.  Perhaps that will still cause the
crash.  Then debugging is simpler: stick "gdb --args" in front to run
gdb on gdb.

Could you clarify? Are you saying to do "M-x gdb gdb--args" in Xemacs?

When you run gdb in xemacs, xemacs should show you the arguments.
This may be --fullname or --annotate=2 or even -i=mi.

Once you see how it is invoking, go to the shell and type:

gdb --args gdb --fullname ... whatever else ...

This will work provided the crash happens early, as you said in
comment #11

I just realized you're debugging a release build of GDB, most likely an
optimized build without debug info.  If you build a debug build of GDB from
sources ("-O0 -g"), chances are a backtrace on that error would be (more)
complete.  You'll need it to do the debugging Tom is suggesting too, anyway.

What does "-O0" do? I don't see in in gdb man page.

He means that you need to rebuild gdb, this time with debugging
symbols, so that you get a good stack trace.  -g and -O0 are compiler
options.

Ok. How do I exactly do that? Do I need to find the source code for gdb and
recompile it with -g and -O0? Sorry, I am not as skilled as any of you yet ;)

I am not experienced with Windows/Cygwin, but yes, he meant you need to get the
GDB source and compile it with -g and -O0.  It would be interesting if you
could build using the latest CVS version.  To get it, you can do a:

"cvs -d :pserver:anoncvs@sourceware.org:/cvs/src co gdb"

[Assuming CVS is installed on your system.]  It will checkout the source code
inside a directory called "src/".  Then, you can compile GDB:

$ cd src && mkdir mybuild && cd mybuild
$ ./configure CFLAGS='-g -O0' # check for missing deps here, install them
$ make

If everything works, you should have a GDB binary on the "gdb/" directory
(inside "mybuild/").  Then, you can try to reproduce the error with it, and get
a proper backtrace from it.

Thanks for the help, Sergio.

So I downloaded the files and the src folder was in the desktop. I did the
./configure CFLAGS='-g -O0' command when the current directory is .../src and I
got the following below.

The first dependency that configure can't find is "gnatbind". I tried searching
online for gnatbind source code or executable but I can't find it anywhere. I
also did "locate gnatbind" and "which gnatbind" and it is non-existent. Any
ideas where I can find it?

Ok, I also tried to "configure" the GDB source code that is downloadable
through Cygwin and I was able to get the same results above.

I went through the Cygwin setup to look for dependencies, and I was able to
install some of them successfully (and I was unable to find others). The output
is below:

Hi
I can reproduce this easily with current (24/7/2013) cygwin which has gdb
version 7.6.50.20130508-cvs 
It appears when using the "-cd" argument to gdb (as used by xemacs gdb.el),
i.e.

$ gdb -cd . your_executable.exe

I've managed to get the gdb source from cygwin and compile it after

../gdb-7.6.50-2/configure CFLAGS="-g -O0" --disable-gdbtk
--with-system-readline

The error is then the same, and the backtrace is as below

$ gdb --args gdb  -cd .

This might point to a bug in cd_command.

I had a look at applying the patch from Keith Seitz 2013-05-22 used to fix a
similar assert, as mentioned by the OP. I didn't do this careful enough
probably, but it didn't solve the problem. This seems to make sense to me as
this patch is related to find_frame_funname, while here it is the command line
processing.

HTH

Kris

PS: I didn't try current CVS gdb. I have no idea if cygwin has special fixes
for gdb.

Hi
I tried this now with  7.6.50.20130801-cvs. No problem there whatsoever, both
on cygwin and Ubuntu. So, something must have changed in CVS since the
cygwin-special fixing the problem. I guess this can be closed therefore

ah well. the problem disappeared with current cygwin (7.6.50.20130728-cvs) as
well. it seems that somebody is faster than me!
