Filter::Handle Issue in 5.8+

Well {bless \my $inner, shift;}, what a well-documented problem report!

Do either of these URLs help?

1. "Tied methods like FETCH etc. may now safely access tied values, i.e.
     resulting in a recursive call to FETCH etc. Remember to break the
     recursion, though."

    at http://use.perl.org/articles/03/09/26/2231256.shtml?tid=6

or....

2. "A change to self-tying of globs has caused them to be recursively
     referenced (see: Two-Phased Garbage Collection in the perlobj manpage).
     You will now need an explicit untie to destroy a self-tied glob. This
     behaviour may be fixed at a later date."

Good luck tracking this down.

Simon
