test_curses is currently causing the test runs to abort on the FreeBSD 6.4
and 7.2 buildbots.
I can reproduce this on a FreeBSD 7.2 /amd64 machine by doing
./python Lib/test/regrtest.py -uall test___all__ test_curses
This dumps core, and the traceback points at the call to delwin() in
PyCursesWindow_Dealloc, but it's far from obvious (to me) what's going
wrong. wo->win is not NULL here, and appears to point to a valid WINDOW.
However, stdscr is NULL! As far as I can tell, this shouldn't happen.
test_curses by itself doesn't crash, unless I add an 'import readline' or
'import rlcompleter' to the top of test_curses.py.
I expect to have access to the FreeBSD machine for a few more days. Any
hints about what to try next would be appreciated.
