Description Jure Repinc 2011-10-12 04:37:59 UTC

Everytime I try to run an OpenGL app I get a "Program received signal SIGSEGV, Segmentation fault error." Even if I try to run glxgears I get this. I've compiled glxgears and mesa with debug info and this is what I get:

[New Thread 0x7ffff3a39700 (LWP 2134)]
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
Program received signal SIGSEGV, Segmentation fault.

Mesa is from git (ae1153c)

This should in Mesa master now. Could you try it?

Comment 2 Marek Olšák 2011-10-14 06:08:35 UTC

I meant "This should be fixed in Mesa master now".

Comment 3 Jure Repinc 2011-10-14 10:55:46 UTC

Just tried with latest code from git and the crash is gone. Thank you very much for the fix!
