Mondarchive crashes with "buffer overflow detected" while building catalog

[melevittfl@…]

Hi,

I'm trying to use mondoarchive on a Fedora Core 5 system to backup the system to an ext2 partition on an external usb hard disk.

While creating the catalog, Mondoarchive gets to about 93% done and then crashes. Output of stack trace and log to follow:

*** buffer overflow detected ***: mondoarchive terminated

The other time I've seen this problem it was due to a circular reference on the system. Try to find them with find|ls to see if there are (circular links).
