I think the main difference stems from when Clang processes the typedef type.
In the earlier test case, while processing the members of a struct, we
encounter the typedef during the creation of the type for the member variable
"outside." During this typedef creation, the scope is determined based on the
typedef's context, which is a CXXRecordDecl (while in the RegionMap, we store
ClassTemplateSpecializationDecl). In the example above, however, the typedef is
created while emitting the global variable "g," and the context for the typedef
is a ClassTemplateSpecializationDecl, which can be found in the RegionMap,
thereby setting the correct scope for the typedef.
