[LLVMdev] Problems when refining type
...maybe I'm way off base.
-------------
#include "Core.h"
int main()
{
LLVMTypeRef a = LLVMPointerType(LLVMOpaqueType(), 0);
LLVMTypeHandleRef ha = LLVMCreateTypeHandle(a);
LLVMTypeRef atypes[1] = { LLVMResolveTypeHandle(ha) };
LLVMRefineType(LLVMResolveTypeHandle(ha), LLVMStructType(atypes, 1, 0));
LLVMTypeRef b = LLVMPointerType(LLVMOpaqueType(), 0); // assert here
....
}

The assertion text is:

It looks like a bug; the type map is somehow holding onto a stale
pointer to an opaque type. That said, refining a pointer type is a
very unusual operation; I'd suggest sticking to refining opaque types.
