jrozhon created an issue (kamailio/kamailio#4154)

Description

I have Kamailio configured to act as a gateway between SIP and XMPP in my lab setup. I only have module configured, no routing is implemented yet. When handshake with XMPP server (Prosody) occurs, Kamailio crashes.

Troubleshooting

I cannot use newer version of kamailio as it crashes because of presence module. Older versions up to 5.5.7 behave the same.
If i get backtrace right crash is caused by a problem with parsing the incoming xml, but it seems fine to me.

Reproduction

Have prosody xmpp server configured to accept component connection from kamailio.

In kamailio have xmpp.so module loaded with following parameters set:

modparam("xmpp", "backend", "component")
modparam("xmpp", "gateway_domain", "kamailio-dns")
modparam("xmpp", "xmpp_domain", "xmpp-dns")
modparam("xmpp", "xmpp_host", "xmpp-dns")
modparam("xmpp", "xmpp_port", 5347)
modparam("xmpp", "xmpp_password", "shared-password")
