Dear Cygwin maintainer
Since last X-Cygwin update several of my X-Win applications are not
working properly.
Googling cygwin xorg 1.17 crash gave many posts reporting probably
similar issues but I couldn't find a fix for the error. I also looked at
the Cygwin-FAQ and mailing list without real success.
The issue appeared using a long-time tested DOS script launching xmgrace
which failed with a message telling A fatal error has occurred and
Cygwin/X will now exit. And other XWin programs were not working
properly. So I tried to make a fresh install of X-Cygwin (32 bits) on
another computer and went through the procedure explained on page
http://x.cygwin.com/devel/backtrace.html
which produced the debug info attached as backtrace for X server
crashing at startup.txt. The X Server crashed when the r command was
launched and a copy of the Windows error message is provided at Capture
of Windows error message.txt. I checked that no other X Server was then
running and clicked Ok button to finish the procedure.
The content of the file /var/log/xwin/XWin.0.log is listed at the end of
the first attached file.
I also tried to install the most recent xlaunch program as suggested here
https://www.cygwin.com/ml/cygwin-xfree/2015-02/msg00089.html
but it did not solve the issue.
Sorry for asking something that might be FAQ but as I told I could not
find a clear answer elsewhere and indeed xlaunch reproduced the error
consistently.
Thanking you in advance for your assistance, and of course for providing
this invaluable software that is cygwin.
Regards
