Mailing List Archive: Warning in Perl code: Attempt to free unreferenced scalar

I figured it out by process of elimination.
I was passing in an anonymous sub to an embperl sub and
my sub did this:
sub {shift->{a} . shift->{b}}
when there was only one argument.

So Embperl's only role here was in obfuscating the stack.
