Solve the following python programming problem given the following code:
def __call__(self, environ, start_response) : 
    response_body = [] 
    def catching_start_response(status, headers, exc_info = None) : 
        start_response (status, headers, exc_info) 
        return response_body.append 
def runapp() : 
        appiter = self._app (environ, catching_start_response) 
        response_body.extend (appiter) 
        if hasattr (appiter, 'close') : 
            appiter.close () 
p = Profile () 
    p.runcall (environ) 
    body = ''.join (response_body) 
    stats = Stats (p, stream = self._stream) 
    stats.sort_stats (* self._sort_by) 
    self._stream.write (('-' * 80)) 
    self._stream.write (('
PATH: %r
' % environ.get ('PATH_INFO'))) 
    stats.print_stats (* self._restrictions) 
    self._stream.write ((('-' * 80) + '

')) 
    return [body] 

    
    

    Fix the buggy line: p.runcall (environ)
