Python Coredump on FreeBSD

[Harald Schneider]

I was able to locate the bug:

When I call

re.compile(.......).search(.....)

in sequence a few times, then the regular expression module re causes this
coredump. It's implementation must differ from other platforms. It looks
like it trashes memory and finally crashes. Maybe re is not threadsave on
FreeBSD.

Bug isolated, but no solution yet ... I'll try to test in a non-threading
environment to see, if there is a dependency ...

Thanks a lot,
Harald
