You had no replies, so I thought I'd try it. If it is any consolation I reproduced your problem easily, I'm using XP SP2 with ActiveState perl 5.8.8 and PAR 0.952. I spotted a comment in the PAR documentation concerning Glade and stack unwinding as a bug - possibly related?
As an alternative work-around:
use strict ; 
use warnings ;
use Win32  ; 

sub die_handler { Win32::MsgBox ("Error :  @_" ,  0, $0 )  } ; 
eval {die "ARRG" }; 
die_handler ("$@") if $@;
print "Ended OK\n";

Seems to work correctly. I suggest you use this method of trapping die's, and report a bug to the PAR guys.
