on bug 66331
from Dieter Nützel
With current Mesa CVS (10.0.0! ;-) on RV730 AGP I get this,too. Pure LLVM (3.3 stable) bug, NOT sb. setenv R600_DEBUG nollvm Works OK. Nice link, Grigori! Application: konqueror (4.11.2) KDE Platform Version: 4.11.2 Qt Version: 4.8.5 Operating System: Linux 3.12.0-rc3-1-desktop i686 Distribution: "openSUSE 12.3 (i586)" -- Backtrace: Application: Konqueror (konqueror), signal: Segmentation fault Using host libthread_db library "/lib/libthread_db.so.1".
