Fails Rev. 164509 (ICE)
Mikael, I think your patch could be the culprit (Rev. 164494, PR 45648).

------- Comment #3 from mikael at gcc dot gnu dot org 2010-09-22 15:12 -------
Patch 4/5 in the patchset(http://gcc.gnu.org/ml/fortran/2010-09/msg00369.html)
changed this:
secss = ss;
/* Look for the SS for this function. */
while (secss != gfc_ss_terminator
&& (secss->type != GFC_SS_FUNCTION || secss->expr != expr))
secss = secss->next;
[...]
if (secss == gfc_ss_terminator)
{
/* Elemental function. */
to:
if (ss->expr != expr)
{
/* Elemental function. */
But to be equivalent to the loop exit condition, it should be:
if (ss->expr != expr || ss->type != GFC_SS_FUNCTION)
{
/* Elemental function. */
