The patch at the end of this message will at the very least keep X
servers from being fried on the ``marker does not point anywhere''
bug.  However, I still don't know why it happens, especially since I
have no way of reproducing it (it's never happened to me).

If the bug hits after you install this patch, let me know what gets
printed out...
