Can you please report a more complete bug report that includes at least the
version numbers of what you are running ?

mp1 bug reporting: http://perl.apache.org/docs/1.0/guide/help.html#How_to_Report_Problems
mp2 bug reporting: http://perl.apache.org/docs/2.0/user/help/help.html#Reporting_Problems

But after having looked at mp1's code, I suspect you are running mp1 and that there
is a bug there. Can you try applying this patch ?

But one thing is for sure, in mp1, this is a bug, since it's setting $0 but
failing to reset it back.
