Confirmed.



Fails with GCC 4.5/4.6/4.7/4.8 in gfc_verify_binding_labels:



      bind_c_sym = gfc_find_gsymbol (gfc_gsym_root, sym->binding_label);

      if (bind_c_sym != NULL

          && strcmp (bind_c_sym->name, sym->binding_label) == 0)

        {

          if (sym->attr.if_source == IFSRC_DECL

              && (bind_c_sym->type != GSYM_SUBROUTINE

                  && bind_c_sym->type != GSYM_FUNCTION)

              && ((sym->attr.contained == 1

                   && strcmp (bind_c_sym->sym_name, sym->name) != 0)

                              ^^^^^^^^^^^^^^^^^^^^

Here, bind_c_sym->sym_name == NULL.
