pdb in 3.0 very buggy (Win XP Home)

[Aaron Brady]

Hi, got a freeze when running 'pdb' in 3.0.

The program executes correctly with the command 'c', but freezes part
way through when running successive 'n' commands. Platform Windows XP
Home. Python 3.0 (r30:67507, Dec 3 2008, 20:14:27) [MSC v.1500 32
bit (Intel)] on win32. The 'list' command was also not working
properly, printing '[EOF]' many places, even when prompted with
arguments for 'first' and 'last'.

Hi, got a freeze when running 'pdb' in 3.0.

This is a known issue because of the rewrite of the IO library in 3.0. It will
hopefully be fixed in 3.1. See http://bugs.python.org/issue3618 for more
information.
