Could be anything.  My guess is that it's a C library bug,
as those arguments to getdirentries look bogus.  Perhaps
fdopendir doesn't work properly?  You might want to look
into it further, with a debugger.

Also, please see the fdopendir bug in FreeBSD 8 that is
documented in
<http://lists.gnu.org/archive/html/bug-gnulib/2011-02/msg00052.html>.
Presumably the same bug is in FreeBSD 7.

Is fdopendir declared on your platform?  If not, perhaps tar
should not use fdopendir when it's not declared.
