Summary: Guns of Icarus Online segfaults on startup since
AMDGPU: Partially fix control flow at -O0
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW

Short Guns of Icarus Online startup trace (truncated by segfault)
Guns of Icarus Online segfaults (or sometimes hangs) on startup with current
Mesa and LLVM. I have bisected the segfault to LLVM r282667.
The backtraces for the segfaults vary. Some of the segfaults are inside malloc
/ free, indicating possible memory corruption.
I have attached an apitrace recorded using a bad LLVM revision. While the game
consistently segfaults (or hangs), replaying the trace does not result in a
segfault every time.
Here is also a longer trace of the full startup sequence recorded using a good
LLVM revision:
http://constexpr.org/tmp/GoIO-radeonsi.2.trace.xz (82 MiB)
GPU: R9 380X
Kernel: 4.7.5-gentoo
Mesa: git-024c207
LLVM: r283076
