        <pre>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:
<a href="https://github.com/ConfettiFX/The-Forge" target="_blank" rel="noreferrer">https://github.com/ConfettiFX/The-Forge</a>
I maintain a &#39;lite&#39; edition so it is easier for me to embed into other
projects, which is probably easier to test with:
<a href="https://github.com/boberfly/The-Forge-Lite" target="_blank" rel="noreferrer">https://github.com/boberfly/The-Forge-Lite</a>

I narrowed it down to this line crashing in the RADV vulkan driver when running
the 01_Transformations example:
<a href="https://github.com/boberfly/The-Forge-Lite/blob/v1.27/src/Renderer/Vulkan/Vulkan.cpp#L477" target="_blank" rel="noreferrer">https://github.com/boberfly/The-Forge-Lite/blob/v1.27/src/Renderer/Vulkan/Vulkan.cpp#L477</a>
From:
<a href="https://github.com/boberfly/The-Forge-Lite/blob/v1.27/src/Examples/01_Transformations/01_Transformations.cpp#L226" target="_blank" rel="noreferrer">https://github.com/boberfly/The-Forge-Lite/blob/v1.27/src/Examples/01_Transformations/01_Transformations.cpp#L226</a>

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]

32 43 89 5c 74 0c 8b 4e 04 4b 89 34 74 85 c9 74 2e 83 e9

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.</pre>
