Hi

I get a crash when running xfontsel under latest cygwin-1.5.8
and all the latest cygwin C packages installed.

Please try the latest cygwin1.dll snapshot.  It sounds like this problem 
may be fixed by it.  I would like positive confirmation of this.

There is no indication from this bug report that this is in any way
related to the problems fixed by the snapshot and now by the 1.5.9-1
release.  The only fix in the cygwin snapshot was a work around for a
cygwin heap problem which manifested on certain Windows XP or 2000
systems.

There is nothing that would address a SEGV.  Judging from Volker's stack
trace, it looks like the problem is in the program itself, rather than
the Cygwin DLL, too.

 From your description of the fix:

Since I have "fixed" the problem with people being unable to run some
programs due to cygheap allocation, I should release a new version of
cygwin ASAP.

We've been having problems with emacs bombing, XWin.exe bombing, now 
xfontsel bombing (without any changes being made to xfontsel from the 
pervious release), and you talked about a fix for apps dying on 
startup... sounded related to me.

Dunno... it is happening with too many programs now to suspect the 
program itself.  We need to compile some better information about these 
crashes but I have been busy working on packaging and such.  I think we 
can start looking into this real soon now.
