Crash of Oddworld

Crash of Rochard

For additional info, I've compiled latest mesa git with llvm 4.0 (stock version of Fedora 26) and Unity games are working.
But I've no idea whether the problem is in llvm 6.0 itself, or how mesa is using newest llvm library.

Thanks for the report. Is this still an issue? The traces look subtly different...

Do you have backtraces with symbols? Make sure you compile Mesa with debug symbols enabled.

other unity games affected:
candle
silence
grow home
pulse
mousecraft
wasteland 2
broforce
habitat
munin
the last tinker
agatha christie the abc murders
plague inc evolved
pillars of eternity
monochroma
foosball
superhot
layers of fear
glare
space hilk ascension
hitmango
leisure suit larry reloaded
action henk
never alone kisima ingitchuna
interplanetary
cities skylines
cities skylines snowfall
cities in motion 2
star horizon
oddworld




I tried to env variable: 
R600_DEBUG=vs,tcs,tes,gs,ps,cs ./SUPERHOT.x86_64
but there was no debug output (not like the variable with glxgears...)

Yes, the problem is still there, tested with mesa git 9f9177d, llvm git e58aca6 (and clang 9f9177d).
Unfortunately I am unable to provide backtrace with symbols now since I've upgraded to Fedora 27 and have problems with building debuginfo package.

I wanted to add The Longest Dark to your list as this seems very close to the issues I'm having with it on Arch Linux. The strange thing is I'm experiencing other, random OpenGL and radeon errors and bugs, with Unity x64 binaries being the only ones that will no longer load, period. We have both a runtime and native steam client on Arch and the 32bit blob for TLD does work after a very slow start and long error output.

 Here's some basic system info:

OpenGL vendor string: X.Org
OpenGL renderer string: AMD CAPE VERDE (DRM 2.50.0 / 4.14.10-1-ARCH, LLVM 5.0.1)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.3.1
OpenGL core profile shading language version string: 4.50

"Oxygen Not Included" also crashes on startup. Backtraces attached.

bug still present with versions:
mesa-filesystem-18.1.0-0.2.gita5053ba.fc27.x86_64
llvm-libs-7.0.0-0.1.r323994.fc27.x86_64
clang-7.0.0-0.1.r324055.fc27.x86_64

always segfaulting.

*** Bug 100990 has been marked as a duplicate of this bug. ***

still segfaulting regularily or have weird outputs (flickering screen)

with f28, 4.17rc1 (amdgpu)

    Device: Radeon RX Vega (VEGA10, DRM 3.25.0, 4.17.0-0.rc1.git3.1.fc29.x86_64, LLVM 7.0.0) (0x687f)
mesa-libGL-18.1.0-0.40.git52e93e3.fc28.i686


could be related to the vsync: when the game does start but flickers, when i change the vsync on and off a couple of time, sometimes it gets normal. Still segfaulting on the exit of the game

it seems the segfaults have improved lately... Much less, the games do start more often

I've done some more tests,  the games all start more or less correctly on fedora 28. Still several "display bugs" like flickering screen or so, but they do start. Even it segfaults at the end, it's better than before when it segfaulted when opening the screen.

So this bug is kind of fixed for me in fc28
mesa:
mesa-libGL-18.0.1-1.fc28.x86_64

llvm:
llvm-6.0.0-11.fc28.x86_64


and it improves even more with the copr build of che
