X server segfault problem

- Subject: X server segfault problem
I'm having a problem with cygwin 1.7.7
and X version 188.8.131.52 where an OpenGL
application from perl using the Mesa3D
binding dies in the test with a segfault:
A fatal error has occurred and Cygwin/X
will now exit.
Caught signal 11 (Segmentation fault).
Please open /var/log/xwin/XWin.0.log
for more information.
When I close the popup alert, X exits.
The XWin.0.log only has Segmentation
fault at address 0xe.
I've been unable to determine if the
problem is in the perl OpenGL module
code or in the updated X+GLX+Mesa3D.
To reproduce, just download the perl
OpenGL module source:
and extract the directory. cd to the
OpenGL-0.64 directory and run the following
( set -x ; perl Makefile.PL ; make ; make test ) 2>&1 | tee ../pogl-x-crash-log.txt
which should configure, build and run the test
for this module. You will need to have gcc,
perl and opengl installed in your cygwin.
Any help appreciated since I can no longer
develop on cygwin since the X server started
crashing...not even to fix the problem (if
it is the OpenGL module code).
Thanks in advance,
