stacktrace from game log file

"LLVM triggered Diagnostic Handler: Ran out of VGPRs for spilling SGPR"

The game Planet Explorers crashes after a few minutes, the log file is flooded
with this error message.

Additional error messages:
radeon_llvm_compile: Processing Diag Flag
LLVM failed to compile shader
EE si_state_shaders.c:647 si_shader_select - Failed to build shader variant
(type=1) 1

The problem may have started with mesa 11.0 but I'm not sure, I don't play it
very often. The game runs on unity 5.

Attaching backtrace and stacktrace from the log file. There is also a memory
map I could attach.

OpenGL info from the log file:
Version:  OpenGL 3.0 [3.0 Mesa 11.0.5]
Renderer: Gallium 0.4 on AMD PITCAIRN (DRM 2.43.0, LLVM 3.7.0)
Vendor:   X.Org
VRAM:     2048 MB

Hardware is a Radeon HD 7870
