--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
We're missing a check for cv-qualifiers in
__pointer_to_member_type_info::__pointer_catch that needs to be done before we
compare the pointees. Both pointees have type void() so we need to compare the
cv-quals before that info is lost.
