Python Coredump on FreeBSD

[Harald Schneider]

Sorry -- file attached.

The file is read completely and split into lines. Each line is split by the
":". Comments # are ignored.
The resulting datastructure is an array of arrays assigned to self.lib

The code calling re is this:

            for filter in self.lib:
                    if
re.compile(filter[1],re.I|re.M|re.S).search(self.msg[filter[0]]) <> None:
                        return(filter[2])

filter[1] is the pattern, [2] is the returncode, [0] is a key of a
dictionary containing the strings which are searched.

As you see, the only special thing here are some long OR-chained regex which
seem to exhaust the limited stack on BSD.
Even splitting them to shorter expressions causes a crash. The Linux and
Win32 implementation are not affected ...
