Hello,
I am using the oibaf mesa-vulkan-drivers which I believe is the latest git
(just updated to 30th May 2019 build here 19.2~git1906010730.755906~oibaf~b
running Linux Kernel 5.0.2 on Ubuntu 18.04). I have recently got segfaults when
running vkCreateDescriptorPool with The-Forge which has worked perfectly before
in the past on multiple OSes/Vulkan implementations, including RADV:
https://github.com/ConfettiFX/The-Forge
I maintain a 'lite' edition so it is easier for me to embed into other
projects, which is probably easier to test with:
https://github.com/boberfly/The-Forge-Lite
I narrowed it down to this line crashing in the RADV vulkan driver when running
the 01_Transformations example:
https://github.com/boberfly/The-Forge-Lite/blob/v1.27/src/Renderer/Vulkan/Vulkan.cpp#L477
From:
https://github.com/boberfly/The-Forge-Lite/blob/v1.27/src/Examples/01_Transformations/01_Transformations.cpp#L226
The error I get is pretty vague:
[1185298.570160] MainThread[39052]: segfault at c ip 00007fe119abd604 sp
00007ffc01e6afc8 error 4 in libvulkan_radeon.so[7fe11992b000+230000]

I can only say that roughly a month ago this was running fine on an older RADV
version. I am using the latest Vulkan 1.1.106 SDK from LunarG as well.
Hardware: HP z620 w/ 2x Xeon E5-2680v2, AMD Radeon Vega Frontier Edition 16GB
I hope I have enough information here to explain the issue.
