[Vulkan] Non uniform sampling of sampler2DMSArray is crashing the driver

The driver reports via VkPhysicalDeviceDescriptorIndexingFeatures that shaderSampledImageArrayNonUniformIndexing is available. So it should be legal to call the following code in a shader:

layout (...) uniform sampler2DMSArray textures2DMSArray[some size];

...

color = texelFetch(textures2DMSArray[nonuniformEXT(textureIndex)], ivec3(uv * size, layer), int(sample));

But it's crashing the driver. It doesn't crash when removing nonuniformEXT. The callstack goes quite deep:

Did you also enable that feature when creating the device? It being available as a feature of a physical device is not enough, it needs to be explicitly enabled as well.

Sure. I'm enabling VkPhysicalDeviceDescriptorIndexingFeatures.

Hi @pascal-gw 

Could you please provide a minimal code which can reproduce this problem?
