--- Comment #2 from Mikael Morin <mikael at gcc dot gnu.org> 2011-08-12 11:54:27 UTC ---
In gfc_expr_to_initialize, we copy an expression,
result = gfc_copy_expr (e);
and then change it to something else:
/* Change the last array reference from AR_ELEMENT to AR_FULL. */
for (ref = result->ref; ref; ref = ref->next)
if (ref->type == REF_ARRAY && ref->next == NULL)
{
ref->u.ar.type = AR_FULL;
for (i = 0; i < ref->u.ar.dimen; i++)
ref->u.ar.start[i] = ref->u.ar.end[i] = ref->u.ar.stride[i] = NULL;
result->rank = ref->u.ar.dimen;
break;
}
Not very surprising that it fails.

The following (reduced from the FoX library m_common_attrs.F90) seems to cause
an ICE with gfortran 4.7.0 (r177982) - Dominique Dhumieres suggests that this
is probably related to r177970.
module m_common_attrs

type dict_item
end type dict_item
type dict_item_ptr
type(dict_item), pointer :: d => null()
end type dict_item_ptr
contains
subroutine add_item_to_dict()
type(dict_item_ptr), pointer :: tempList(:)
integer :: n
allocate(tempList(0:n+1))
end subroutine add_item_to_dict
end module m_common_attrs

... or rather r177956 (the other commit was on the 4.6 branch).
At least it is known to work at r177931 and fails at r177982.

I removed the regression marker as the regression (cf. comment 7 to comment 12)
has been fixed for the affected 4.6 branch and the 4.7 trunk.
I leave the PR open in case someone wants to backport (to 4.5 and/or 4.4) the
original patch (comment 5) with the follow-up patch (comment 11). The original
bug is about an ice-on-valid-code issue.
