Why not let setup.py do it?  Not likely to be relavent, but...

Wierd.  Let me try:

$ ../../build/python regrtest.py -u curses test_curses.py
test_curses
test test_curses crashed -- _curses.error: curs_set() returned ERR
1 test failed:
    test_curses
Segmentation fault (core dumped)

Holy crap!

Definitely seem to be freeing things we shouldn't.

I'm guessing noone's run test_curses in a while.

Are you using 2.2, or stuff from CVS?

Cheers,
M.
