And do you have the matching version of emacs-debuginfo installed?
The lack of information in the backtrace of Thread 1 makes me think
that you might not.



I think I do:

$ cygcheck -f /usr/lib/debug/usr/bin/emacs-X11.exe.dbg
emacs-debuginfo-24.3.93-3
Also, gdb does not complain about a version mismatch, although the path to the symbols looks a little strange to me (note the // in the middle): 

$ gdb /usr/bin/emacs-X11
GNU gdb (GDB) 7.8
[...]
Reading symbols from /usr/bin/emacs-X11...Reading symbols from /usr/lib/debug//usr/bin/emacs-X11.exe.dbg...done. 
done.



GLib (gthread-posix.c): Unexpected error from C library during
'pthread_mutex_lock': No error.  Aborting.


I would also suggest that you install glib2.0-debuginfo, to see if we
can get more information about this Glib abort if it happens again.
Finally, please make sure that you're using the latest versions of gdb
and Glib (there were new releases of both last week).

Thanks.

Ken
I'll see to it. I'm not sure whether Glib is relevant here. I had a second crash barely 15 min after the first one which I did not get round to report yet (see below). This one does not seem to point to Glib. 

regards,
Markus
