Thanks for the report.  The culprit line is:
           ngettext ("1 byte (1 B) copied",
                     "%"PRIuMAX" bytes (%s) copied",
                     MIN (w_bytes, ULONG_MAX)),
           w_bytes,
           human_readable (w_bytes, hbuf, human_opts, 1, 1));

What version of gettext do you have installed?  What locale are you using?
 My guess is that the PRIuMAX is being mishandled by your older version,
and passing an invalid string to ngettext; see
http://lists.gnu.org/archive/html/bug-coreutils/2006-07/msg00087.html for
a similar report.  You should also try coreutils beta 6.1, which requires
a newer gettext in an attempt to avoid these types of coredumps.
