--- Comment #4 from Sven Arvidsson <sa at whiz.se> ---
Hi,

I had the same problem on a previously working system, with a very similar
looking backtrace: 

Thread 1 "vulkaninfo" received signal SIGFPE, Arithmetic exception.
0x00007ffff62aa2f3 in radv_pipeline_scratch_init
(pipeline=pipeline at entry=0x555555a66c50, device=<optimized out>, 
    device=<optimized out>) at ../../../../src/amd/vulkan/radv_pipeline.c:117

I noticed that running vulkaninfo as root, or as another user worked. 

Just deleting the file ~/.cache/radv_builtin_shaders fixed it here. 

I'm not sure if the file simply got corrupt due to me killing a vulkan app
abruptly or if it had something to do with switching between 64bit and 32bit
apps and drivers?

(Not entirely sure how to regenerate the file to recreate the bug either, just
running vulkan-smoketest doesn't seem to suffice)
