There is getPointerType(RetQT) just above, shouldn't it be something like getPointerType(RetQT, <correct address space>)?
Or RetQT should have had the correct address space, but for some reason it was lost?

I totally agree with you.
I'm unfamiliar with Clang Qualtypes
and how clang QualTypes' addrspace info
match to llvm types' addrspace info,
so I shared a quick dirty fix to at least share a direction.
