For the record, this happens on FreeBSD 8 as well.

It seems it is still the same bug as what I reported back in March 2009 on the Python-dev list.

If you run the test stand-alone with ./python Lib/test/regrtest.py -uall test_curses it passes and prints "1 test OK".

If you add something like test__all__ before it it will crash with a SIGSEGV: segmentation fault (core dumped).

Mark's condensed test case switches to a SIGBUS, which is a bit different.

Mark, did your initial backtrace look like this:
