And the backtrace:

in mio_charlen function, it run into
if (iomode == IO_OUTPUT)
1665        {
1666          cl = *clp;
(gdb)
1667          if (cl != NULL)
1668            mio_expr (&cl->length); <<<< ICE HERE!
1669        }

(gdb) p *cl
$7 = {length = 0x1, next = 0x0, backend_decl = 0x0, resolved = 0}

The character length is an expression, not a constant integer.
