--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. There's a not released SSA name in the IL that does not have a def
stmt. The issue is once again a type that wasn't properly gimplified:
(gdb) p debug_generic_expr (new_tree)
character(kind=1)[1:.y]
with TYPE_SIZE being
SAVE_EXPR <(bitsizetype) (sizetype) .y.5_2 * 8>
there's a DECL_EXPR missing for this variable.

--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think those types:
character(kind=1)[1:.y] * y;
don't really make sense for the character(:) allocatables, I think much better
would be to leave the TYPE_MAX_VALUE from TYPE_DOMAIN out, making it [1:].
[1:.y] nicely expresses the intent, in most places y (if it is not NULL) should
point to [1:.y] array. But if we emit a DECL_EXPR for it, it will be just
wrong,
the middle-end expects the C/C++ VLA behavior, the size is computed once (when
encountering the DECL_EXPR), then the VLA is allocated with it and that is the
size it has from that point on.
The deferred-length (is that the right term) arrays work differently from this
though, the length can be changed at any time. So the VLA length is always
determined from the current value of the .y variable (except in the short spots
where that is updated and the var not yet reallocated).

--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Though, if we make those arrays incomplete, gfc_omp_finish_clause will need to
figure out what size to use. This is in:
if (OMP_CLAUSE_SIZE (c) == NULL_TREE)
OMP_CLAUSE_SIZE (c)
= DECL_P (decl) ? DECL_SIZE_UNIT (decl)
: TYPE_SIZE_UNIT (TREE_TYPE (decl));
if (gimplify_expr (&OMP_CLAUSE_SIZE (c), pre_p,
NULL, is_gimple_val, fb_rvalue) == GS_ERROR)
OMP_CLAUSE_SIZE (c) = size_int (0);
and the gimplify_expr part is what my change added. We'll need to check some
Fortran specific type flags etc. to see it is a deferred-length character and
find the corresponding . variable, though TYPE_LANG_SPECIFIC is NULL on the
ARRAY_TYPE created by gfc_get_character_type_len_for_eltype -> build_array_type
it seems.
