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.
