denyspozniak created an issue (kamailio/kamailio#4314)

Description

The code below causes Kamailio to crash when sending a simple OPTIONS request.
I agree that this is not the most proper way to call the sl function,
but it's probably worth paying attention to this issue.

Reproduction

import KSR as KSR

def mod_init():
    return kamailio()

class kamailio:
    def __init__(self):
        KSR.info('== kamailio init  ==\n')

    def child_init(self, rank):
        return 0

    def ksr_request_route(self, msg):
        KSR.x.modf("sl_send_reply", "200", "OK");
        return 1

Debugging Data

(gdb) bt full.txt

(gdb) info locals.txt

(gdb) list
