Summary: [r300g] Programs crash with segfault Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: Drivers/DRI/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: ncl@privat.dk
In the last week a lot of my program crash with a segfault (OpenSceneGraph, Blender 2.5.3, Make Human etc.). Other program with gallium works ok. They all crash the same way and here are my (gdb) bt:
Program received signal SIGSEGV, Segmentation fault.
