This looks like a bug in perl, not Log4perl. Since Log4perl is pure
Perl, there should never be a panic situation, except if there's a bug
in perl itself.

You might want to write up a reproducable script, and file a bug with
perl via perlbug (which adds your complete perl -V build information for
reference).
