I'm trying to use Filter::Handle in a script I'm writing (it does exact what I want I need) and see that its tests have been segfaulting on Perl 5.8+. Perl 5.6 seems uneffected. The problem lies in this test for the Filter and UnFilter methods:

my $out;
Filter \*STDOUT, sub {
    $out = sprintf "%d: %s\n", 1, "@_";
    ()
};
print "Foo";
UnFilter \*STDOUT;
print $out eq "1: Foo\n" ? "ok 3\n" : "not ok 3\n";

Here is the code to those two methods:

sub Filter {
    my $fh = $_[0];
    tie *{ $fh }, __PACKAGE__, @_;
}

sub UnFilter {
    my $fh = shift;
    { local $^W = 0; untie *{ $fh } }
}

Perl's internals are not my forte so I don't see or understand what is going wrong. I was hoping someone here could clue me in. The maintainer of the module has his hands full with a few other things right now.

Thanks.
