Long time ago, I had a similar problem with termios TIOCGWINSZ and we patched the port like this: http://www.freebsd.org/cgi/cvsweb.cgi/ports/lang/python/files/Attic/patch-Modules%3A%3Afcntlmodule.c?rev=1.1;content-type=text%2Fplain I believe it was upstream patched at the time but I won't be surprised if something similar was reintroduced. It happens when a Python internal integer type is converted to a native unsigned long. FYI...
