I think we can simply restrict the same_type_p call to type_decls with
TREE_TYPE with CLASS_TYPE_P true or something very close. I'm testing a patch.

It's an infinite recursion affecting the same_type_p call at parser.c:25125
which I added in that patch.

With -fpermissive -std=c++98 just warnings instead of errors are emitted, and
the ICE starts with r204339.
