Perhaps you configured with some other toolkit? That might explain the discrepancy. Does it fix things for you if you add a line 'dpyinfo->connection = -1;' after the existing line 'dpyinfo->display = 0;' in xterm.c's x_connection_closed? Though that might cause a file descriptor leak; I'm not fully following what's going on here, since I can't reproduce the new problem.
