[mod_python] problem using regular expressions in CGI scripts

Can you try running the same code in your own handler, and see where that
takes you, in other words:

httpd.conf:
AddHandler python-program .py
PythonHandler myhandler
PythonDebug

Then the myhandler.py file would have something like

--- snip ---

from mod_python import apache
import re, sys

def handler(req):

    req.content_type = 'text/plain'
    req.send_http_header()
    re.compile( r'foo(\(.+\))bar' )
    req.write('ok')
    return apache.OK

--- snip ---


Note that it is not necessary to print out the traceback - mod_python does
that for you if PythonDebug directive is specified.
