Perl DBD ORA_XMLTYPE binding causes Segmentation fault

Hello all,
I hope someone can tell me how to troubleshoot or solve my Perl problem I am having. There is an Oracle stored procedure(that I have no control over) that I am attempting to access using Perl (use DBI; use DBD::Oracle qw(:ora_types);). The segmentation fault comes on the binding to the first XMLTYPE in the stored procedure. I am able to run the procedure successfully in Oracle SQL Developer so I believe the DB end is working (maybe). I could post all the code if necessary, but it is typical code I see everywhere else on the web. Here is the portion of code that has the trouble:

print "bind 6\n";
eval{
  $query->bind_param_inout(6, \$rtn1, 20000, { ora_type => ORA_XMLTYPE } );
};
if($@){
  print "\$@ = " . Dumper($@);
}
print "bind 7\n";
$query->bind_param_inout(7, \$rtn2, 20000, { ora_type => ORA_XMLTYPE } );

It will print the 'bind 6' and then just fail. When I run it while debugging, is when I see the segmentation fault. The eval catch is never executed not to mention the rest.

Any experience on this issue would be much appreciated!
Thanks
