[mapserver-users] My gis program

[Joe Bussell]

The cleanup errors are due to a poorly written interface to SWIG.  The
code that connects PERL to the underliing C functionality creates ties
using perl hashes.  Some interconnects are not proper hashes.  I have no
idea why at this point, but I do know a hack that will eliminate the
cleanup warnings.  In your mapscript.pm file everywhere you find a
DESTROY method you should return directly if the input is not a hash.  I
offer the following example:

sub DESTROY {
   return unless $_[0]->isa('HASH');
   my $self = tied(%{$_[0]});
   delete $ITERATORS{$self};
   if (exists $OWNER{$self}) {
      mapscriptc::delete_rectObj($self);
      delete $OWNER{$self};
   }
}
