i didn't post code because i don't think it's a problem where one can point at a line and say AHA!
the SWIG module is simply : 
sub method {
    my @args = @_;
    $args[0] = tied(%{$args[0]});
    my $result = C++CODE::method(@args);
    return $result;
}

[download]
and perl grabs the package with 
use lib (<path>)
use (C++ package)

[download]

as one would expect 
my $dsgn = new (c++_object)
$dsgn->(method)

[download]

and these lines work IF done in MAIN. if done in a routine and returned to MAIN; it dumps core.
the object is a PERL HASH; and the address never changes when printed out. at first, i thought that meant the object is still present; but the C++ folks say otherwise.
i'm thinking it's a namespace issue. another perl coder has declared the object as a global OUR. that seems to work only for the case : 
MAIN
my C++object
  C++object = pckA::routine
  pckB::routine(C++object)

PACKAGEA
our C++object
  routine
      new C++object
      return C++object

PACKAGEB
  routine
      my $C++object = @_
      $C++object->method()

[download]

and it ONLY works with OUR! so why is the OUR declaration required? is it a PERL problem with swigged objects or is the C++ code not swig/perl compatable?
