--- Comment #1 from anlauf at gcc dot gnu.org ---
ICE confirmed.  But it is really invalid?  Intel & NAG accept it.

Part of the problem is gfc_element_size.  It calculates a number that
is 8 for -m64, and 4 for -m32, likely sizeof (gfc_charlen_t), instead
of noticing that we have a descriptor for deferred length character.

(OTOH using  character, allocatable :: c(:)  seems to work, so maybe the
real issue is in gfc_typenode_for_spec).
