Bug ID: 95026 Summary: Alien Isolation segfault after initial loading screen/video Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel at lists.freedesktop.org Reporter: haagch at frickel.club QA Contact: dri-devel at lists.freedesktop.org Created attachment 123069 --> https://bugs.freedesktop.org/attachment.cgi?id=123069&action=edit layout asm, segfault is in the first line I've had this for a while during playing around with the compute shader patches, but I do not know whether they are at fault. Running on 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Wimbledon XT [Radeon HD 7970M] (rev ff) with mesa git and very recent llvm 3.9. On the first start of Alien Isolation the game shows the initial loading screen and then the 20th century logo video - while playing this video, Alien Isolation segfaults. With subsequent starts of the game, it segfaults while displaying the loading screen and before getting to the 20th century logo video. Unfortunately I can only provide this backtrace: Thread 31 "WinMain" received signal SIGSEGV, Segmentation fault. [Switching to Thread 0x7fffc816d700 (LWP 18766)] 0x00007fffe98a4387 in ?? () from /usr/lib/xorg/modules/dri/radeonsi_dri.so (gdb) bt #0 0x00007fffe98a4387 in ?? () from /usr/lib/xorg/modules/dri/radeonsi_dri.so #1 0x0000000000000000 in ?? () (gdb) because when I compile mesa with empty CFLAGS, it segfaults, but when mesa is compiled with CFLAGS="-g", then the segfault does NOT happen and the game works nicely. So there's only the assembly gdb shows with layout asm in the attachment... When I use the same mesa build that crashes on radeonsi with intel graphics, it also does not crash, so it's something in the radeonsi driver. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
