backtrace

Trying to play Massive Chalice (http://store.steampowered.com/app/246110/), it
crashes on startup after the logos.

My video card is Radeon HD 7770
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cape
Verde XT [Radeon HD 7770/8760 / R7 250X]

Running Fedora 21, 64bit.

When it crashes, I can see this in the terminal:

I attached a backtrace of the game that systemd's coredumpctl helpfully
generated for me - I tried using gdb to get more info but gdb crashes when
processing the coredump.

I'm not 100% sure it's a driver bug, but it probably is because it seems the
developer tested this on the propritary drivers and it worked for them.

It's most definitely an LLVM R600 backend bug.

Please run the game with the environment variable R600_DEBUG=ps , capture its
stderr output to a file and attach that file here after the game crashed.

Which version of LLVM are you using? The failing shader seems to compile fine
with a current LLVM SVN snapshot (which will in time be released as 3.6).

Elad: You could also try testing llvm 3.5 which is available in updates-testing
(https://admin.fedoraproject.org/updates/gambas3-3.6.1-2.fc21,julia-0.3.3-2.fc21,llvm-3.5.0-4.fc21,mesa-10.4.0-1.20141214.fc21,pocl-0.10-2.fc21,pure-0.62-2.fc21).
I think the update will not be pushed to stable due to dependency errors but
there is a follow-up build already in the making.

Thanks.
