--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This is a FE bug, it calls
6955 if (!se->want_pointer && !byref
6956 && ((!comp && (sym->attr.pointer || sym->attr.allocatable))
6957 || (comp && (comp->attr.pointer || comp->attr.allocatable))))
6958 se->expr = build_fold_indirect_ref_loc (input_location, se->expr);
on se->expr that has TREE_TYPE of integer(kind=4) (a CALL_EXPR f (&a[1])).
There is a warning about interface mismatch, but probably the FE should on
interface mismatch just use an DECL_EXTERNAL decl from the interface rather
than the actual definition.
ICEs since r162491 when -fwhole-file has been made the default, or with
-fwhole-file it started with r145314 when that option has been introduced.
