Bug ID: 91752 Summary: Segmentation fault with specific shader (r600) Product: Mesa Version: 10.6 Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: jonas@wielicki.name QA Contact: dri-devel@lists.freedesktop.org

The given apitrace [1] results in a segmentation fault. I am testing this on a sony notebook with Intel sandybridge integrated GPU and a dedicated radeon.

1) $ xrandr --setprovideroffloadsink radeon Intel 2) $ DRI_PRIME=1 apitrace replay r600-crash-01.trace

Actual Results: Segmentation Fault

Expected Results: The rendering should work correctly.

I could reproduce this with both the mesa-libGL 10.6.3 as shipped by fedora as well as mesa 11.0.0-rc1 freshly compiled with:

./configure --enable-selinux --enable-osmesa --enable-egl --disable-gles1 --enable-gles2 --enable-shared-glapi --enable-gbm --enable-glx-tls --enable-texture-float=yes --enable-gallium-llvm --enable-llvm-shared-libs --enable-dri --enable-xa --enable-nine

(flags blindly stolen from the Fedora package specification)

intel GPU: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) radeon GPU: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M] (rev ff)

The same trace runs without crash on the Intel.
