macOS Sonoma Metal regression: Shader with recursion in an buffer struct causes Compute pipeline compilation crash

[billhollings]

FYI to MoltenVK users:

MoltenVK Vulkan CTS testing has uncovered that on macOS Sonoma 14.0 (23A344), a compute shader containing a recursive buffer struct like so:

struct recurs
{
	int m1;
	constant recurs* m2;
};

passes shader compilation, but causes the compute pipeline compilation to crash with an huge recursive call stack.

This is a regression bug, as it only started occurring on macOS Sonoma.

We've let Apple know, and hopefully this gets patched soon.

The attached Metal sample app replicates this in stand-alone Metal:
