Comment (by anevilyak):
Problem found:
In DwarfTypeFactory::CreateType(), we call GetFullyQualifiedDIEName() on
the type entry. The latter finds the entry to have no name, since it's an
anonymous union, finds neither an abstract origin nor a specification, and
then starts trying to build the name from the namespace. This ends up with
the name of the parent struct, then finds that the entry has no name, and
finishes there. Consequently we just get back the name of the parent
struct as the fully qualified DIE name and thus find it in the type cache
and assign that to it, leading to the observed issue. I'm not really sure
as to the best way to fix that without breaking anything else though.
Hypothetically, assigning it the name "<unnamed union>" while parsing the
DIE might work, since then we'd get a name, fail to find an actual type by
it, and then fall back to looking up the type by ID. Thoughts?
