Unit tests crash on Linux with vulkan-icd-loader 1.3.285

[sandroandrade]

Hi,

In spite of Linux no longer being a standalone target, I'm reporting this because it could potentially impact other Vulkan-based platforms. I'm building the unit tests on ArchLinux and they crash with the following stacktrace when using vulkan-icd-loader 1.3.285. Downgrading to 1.3.279 fixes the issue, not sure if that's a bug in The Forge's Vulkan.cpp or in vulkan-icd-loader itself.
