Debugger is not very useful because the binaries are stripped. Is there a debug version somewhere or should i recompile it myself to have it ?
2008/11/21 Florent Fievez <florent.fievez@fievel.be>:After a grep in the sources, I see the error is from file cygwin-net_wm_icon-support.patch. But i'm not sure that the error is in relation with the crash. I will try to run the program under a debugger.
2008/11/21 Florent Fievez <florent.fievez@fievel.be>:Hello,
I have a crash when opening OpenGL. I have the same configuration than you : ssh -X <host> ; XWin with glx extension activated.
Some of my investigations :
1. It's not caused by the X client OS (SunOS and Linux give the same crash) 2. It's not a problem with our application, glxinfo produce the same problem 3. It seems that the message "GetWindowProp - pWin or name was NULL" is displayed before the crash, see my log in attachement.
I will download and check the XWin sources but I have not a lot of time for debugging it so if someone have the same problem or want to help me ...
Best regards,

Since the application we are developing use OpenGL, it's a big problem for me (I have to use an exceed commercial xserver for testing our application).
So is there a known solution, patch or other to this issue ?I see that you do have the libGL1 package installed. Could you please review my results with GLX:

If you are still having issues, please attach your /var/log/XWin.log as well.
