[Bug fortran/28167] ICE: in fold_binary, at fold-const.c:8239 (temporary character array?)

[rguenth at gcc dot gnu dot org]

------- Comment #2 from rguenth at gcc dot gnu dot org  2006-06-26 08:24 -------
Confirmed.  We end up in gfc_trans_create_temp_array

      size = fold_build2 (MULT_EXPR, gfc_array_index_type, size,
                          TYPE_SIZE_UNIT (gfc_get_element_type (type)));

with type being a record type 'struct array1_unknown', so TYPE_SIZE_UNIT
(gfc_get_element_type (type)) returns zero.  gfc_get_element_type (type)
returns charD.14[1:] (!??), so maybe the fix is to use TYPE_SIZE_UNIT
(TREE_TYPE (... ))) here.  (This doesn't fix it, we also pass size == 0 to the
MULT_EXPR,
so we'll end up with a size of zero here)

So maybe the bug is that size and nelem are both zero...  who knows ;)
