--- Comment #5 from Harald Anlauf <anlauf at gmx dot de> ---
The original testcase hits an assert in trans-decl.c:1704

1698      /* Associate names can use the hidden string length variable
1699         of their associated target.  */
1700      if (sym->ts.type == BT_CHARACTER
1701          && TREE_CODE (length) != INTEGER_CST)
1702        {
1703          gfc_finish_var_decl (length, sym);
1704          gcc_assert (!sym->value);
1705        }
1706
1707      gfc_finish_var_decl (decl, sym);

If the assert is removed, the testcase compiles.
