I am trying to troubleshoot an issue with my perl script (running on windows 7) where it terminates with no discernable error or warning. It is consistently terminating in the midst of a fileno command. I'm not sure if the fileno is throwing a signal that causes the jump to END or what. 

    for my $h (@handles) {
        my $fd = fileno $h;
        if (defined $fd && $fd >= 0) {

This is some debugging I captured with perl -d 

0 /ProcOpen.pm:62:     if (! defined $ProcOpen::isWindows) {
0 /ProcOpen.pm:71:     return $ProcOpen::isWindows;
0 /ProcOpen.pm:94:     my $fd = fileno $fh;
0 C:/perl/site/lib/Wx.pm:154:   UnsetConstants() if defined &UnsetCons
+tants;
0 C:/perl/site/lib/Wx.pm:120: END { unload_dll() }

The UnsetConstants() is the start of the Wx.pm END{} cleanup. Any assistance on what to look for would be very helpful.
