vkcube: seg faults with the dev sim layer enabled

[johnzupin]

This might not be related to vkconfig but I though I would create an issue here first to see if anyone can replicate.

Creating a new layer config with dev sim layer enabled and trying to run vkcube cause vkcube to seg fault.

I'm using this json file from Sasha W's blog post here

This issue only seems to happen on windows, vkcube runs fine with dev sim and these settings on linux.

The configuration used was an Mali T880 one. Such configuration are very different from desktop which I think explain the crash. I tried with a Radeon RX 570 configuration and I could not reproduce the crash.

This said, vkcube should not require any specific features or a large number of resources for anything so it should probably be improved.

It would be great if the Vulkan SDK could ship with a "minimum bar" configuration that we could use to check that vkcube is working and to experience a relevant workflow for devsim so that we could make using this layer nice for the Vulkan developers.

Ran this without using vkconfig and still got a crash.
Tried running with validation layers, but the validation layers didn't throw any warnings.
