Oh now I remember. At the time I wrote that code, and possibly still today, several of the tests in the CTS depended on the reported `SubgroupSize` in the shader...

This is a SPIRV-Cross bug. You should probably file an issue [there](https://github.com/KhronosGroup/SPIRV-Cross/issues).

That would indicate that you (or the layer you're using, since `VK_EXT_shader_object` also supports this) set vertex input strides to be a dynamic state, but you're not calling `vkCmdBindVertexBuffers2()`. According...

> @cdavis5e Yes, I'm calling vkCmdBindVertexBuffers2 and specify strides, but they are ignored in MoltenVK because IsVtxStrideStatic is false. Nothing happens when I use validation layer, no errors, no warnings...

You should probably mark this as a draft for now.

Try turning on argument buffers. Setting `MVK_CONFIG_USE_METAL_ARGUMENT_BUFFERS=2` in the environment should work. I now wonder if we shouldn't advertise `VK_EXT_descriptor_indexing` unless argument buffers are turned on, because it mandates a...

You either need to: * Install a more recent `libc++`; or * Take this up with [KhronosGroup/glslang](/KhronosGroup/glslang/issues). Or, maybe we need to up the minimum OS version that `glslang` is...
