I have not been able to follow this discussion, but there needs to be a
better level of understanding here.  Vlad's asking "why does this fix
the problem" and you're responding "it seems to fix the problem". 
Every time I see something like that, I assume the problem is only
being fixed by accident - I'm a big believer in understanding causes.

get_type_deref looks at the type, and if it is a pointer or reference,
it dereferences it.  I assume that this is because we want to show the
children of pointers to structs and references to structs.  Is that
right?

If you want to show the children of the struct given a reference to a
pointer to the struct, then it should handle that too.  Sounds like it
should check for a reference and _then_ for a pointer, instead of
checking at the same time.

There are probably some missing calls to check_typedef here, too.  I
don't think you can have a typedef to a reference in C++, but you can
definitely have a typedef to a pointer, so it would probably be
advisable to call check_typedef before checking for TYPE_CODE_PTR.
