No, it is a bug in perl.  Anytime perl crashes, it is a bug in perl,
unless the crash was due to a XS module since they have access to
the internals of perl.  However, MHonArc is written in pure Perl.

You are lucky that the signal handler actually worked.

An old version of perl.  What linux distribution are you using?
You may be using a bugging build if you are using the version of
perl provided with an older version of Redhat.  I got in the habit
of always building my own version of perl under Redhat.  However,
the RH 7.2 and 7.3 releases appear to have better builds of perl and
I have not experienced any real problems with them.

The line number is at an eval block.  So something within perl is
probably choking when the eval block is exited.

The only advice I can give you is to either rebuild perl from sources,
or better yet, upgrade to a newer version of perl.  Note, I have not
used Perl 5.4 (5.004x) in awhile, but the code that the debugger is
referencing has been the same for a long time.
