Summary: test_ctypes fails on FreeBSD 4.x

Initial Comment:
$ ./python Lib/test/regrtest.py test_ctypes
test_ctypes
test test_ctypes failed -- Traceback (most recent call
last):
  File
"/home/andymac/dev/python-svn-head/Lib/ctypes/test/test_functions.py",
line 333, in test_struct_return_2H
    self.failUnlessEqual((s2h.x, s2h.y), (99*2, 88*3))
AssertionError: (-1004, 2123) != (198, 264)

This is with a subversion checkout updated to 5am AEST
(Aust) 14Apr06, debug build.

The returned tuple values (s2h.x, s2h.y) appear to vary
from run to run, so it looks like something isn't where
its expected.

This is with a FreeBSD 4.8 i386 system (not
particularly recent), using gcc 2.95.4.  A quick and
dirty test (in C) suggests that its not an alignment
issue for the 2 shorts in the S2H struct.

Ideas for trying to debug this further?
