Category: Python Library Group: Python 2.2 Status: Open Resolution: None Priority: 5 Submitted By: Travis Hume (travishume) Assigned to: Guido van Rossum (gvanrossum) Summary: simple script causes segfault

Initial Comment: I've attached a simple script that uses the poplib to periodically check a mailbox and print the number of messages available.

Seems to work twice, then the third time through a segfault occurs.

The attached script contains a gdb backtrace at the end.

Python v2.2a4 Linux Mandrake v8.1

I'm hot on the trail. The problem is most likely in getaddrinfo(). With a debug build, I get this:

import socket [... refs] socket.getaddrinfo("mail.tenzing.com", 110, 0, socket.SOCK_STREAM) [(2, 1, 6, '', ('63.115.0.25', 110))] ../Objects/tupleobject.c:147 negative ref count -1 [... refs]

I'm deleting your attachment since it contained a password. I'm investigating the crash now.O It's an assert atat Objects/typeobject.c:329
