--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
At least the #c8 testcase got fixed with
r12-619-gfc178519771db508c03611cff4a1466cf67fce1d
but that hasn't been backported to 11.x.
The ICE with int * return type is because POINTER_TYPE has NULL
TYPE_LINKAGE_IDENTIFIER, and cat_type_for is called on such type.

would fix this (or shall we instead test if (!CLASS_TYPE_P (type)) or something
similar?
