I'm having a problem with cygwin 1.7.7
and X version 1.9.3.0 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).
   Server aborting.

   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:

   http://search.cpan.org/CPAN/authors/id/C/CH/CHM/OpenGL-0.64.tar.gz

and extract the directory.  cd to the
OpenGL-0.64 directory and run the following
command:

   ( 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,
Chris
