Looking at the call stack OP posted, -1 is coming as forth parameter of __import__, I *guess* at the first import in site.py or at implicit "import site". I think it'd be helpful if OP also tried if it works: python -S -c -v "print -1, type(-1), id(0), id(-1)" -- Leo -- http://mail.python.org/mailman/listinfo/python-list
