If you install faulthandler on "x86 FreeBSD 7.2 3.x" buildbot, I can create a special branch to add specific code.

Or I can add:

try:
    import faulthandler
except ImportError:
    pass
else:
    faulthandler.enable()

In py3k (eg. in Lib/test/support.py).

But the problem is now different: it looks like the bug was fixed, I don't see crashes anymore on  "x86 FreeBSD 7.2 3.x" buildbot :-)

There was failures on test_concurrent_futures, but Martin fixed it in #10798 (not completly (?) but it's better).

I close the issue because it looks like the crash was fixed. Reopen the issue if the crash occurs again.
