Hi, I've built today the 5.7 debs for kamailio together with latest rtpengine master branch debs (commit 13a7e1d), for raspberry pi and tried to give it a try:

Kamailio crashes on startup, only when rtpengine module is loaded and rtp proxies are queried:

Looks like some bencode issue I'm having but lib bencode version looks ok. So far couldn't figure it out. Note that I also had a kernel bump to 6.1.25-v8+ recently.

Any opinions on this?

Thank you,
Stefan
