Description
When compiling the shader in the attached file with `glslangValidator -gVS --target-env vulkan1.3 3188.frag -o 3188.dbg.spv`, glslang crashes with the following assert:
glslangValidator: /home/arcady/glslang/SPIRV/SpvBuilder.cpp:967: spv::Id spv::Builder::makeMemberDebugType(const spv::Id, const spv::Builder::DebugTypeLoc &): Assertion `debugId[memberType] != 0' failed.

Research direction
Start by reproducing the crash with glslangValidator -gVS --target-env vulkan1.3 3188.frag -o 3188.dbg.spv using the attached glslang.3188.zip. Read SPIRV/SpvBuilder.cpp around line 967 and trace the failing makeMemberDebugType assertion; done means the supplied shader compiles without the assertion and the relevant regression is covered.
