Vulkan validation (error): vkCreateShaderModule(): pCreateInfo->pCode (spirv-val produced an error):
Entry point id '4' uses more than one PushConstant interface.
From Vulkan spec:
There must be no more than one push constant block statically used per shader entry point.
%392 = OpVariable %_ptr_PushConstant__struct_389 PushConstant

Command to reproduce:
spirv-val <input.spv> --relax-block-layout --scalar-block-layout --target-env vulkan1.4

The Vulkan spec states: Each OpEntryPoint must statically use at most one variable in the PushConstant Storage Class unless the PushConstantBanksNV capability is declared (https://docs.vulkan.org/spec/latest/appendices/spirvenv.html#VUID-StandaloneSpirv-OpEntryPoint-06674)
