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: ``` root@pisip:~# sudo dpkg -l | grep kama ii kamailio 5.7.0~rc0 armhf very fast, dynamic and configurable SIP server ii kamailio-dbg:armhf 5.7.0~rc0 armhf very fast and configurable SIP server [debug symbols] ii kamailio-presence-modules:armhf 5.7.0~rc0 armhf SIP presence modules for Kamailio ii kamailio-tls-modules:armhf 5.7.0~rc0 armhf TLS support for the Kamailio SIP server (authentication, transport) ii kamailio-websocket-modules:armhf 5.7.0~rc0 armhf WebSocket module for the Kamailio SIP server root@pisip:~# sudo dpkg -l | grep rtpe ii ngcp-rtpengine 11.4.0.0+0~mr11.4.0.0 all NGCP RTP/media proxy - meta package ii ngcp-rtpengine-daemon 11.4.0.0+0~mr11.4.0.0 armhf proxy for RTP and media streams used in NGCP, userspace part ii ngcp-rtpengine-iptables 11.4.0.0+0~mr11.4.0.0 armhf IPtables extension module for the kernel-space NGCP media proxy ii ngcp-rtpengine-kernel-dkms 11.4.0.0+0~mr11.4.0.0 all IPtables kernel module for the NGCP media proxy - DKMS ii ngcp-rtpengine-recording-daemon 11.4.0.0+0~mr11.4.0.0 armhf recording daemon for RTP and media streams ii ngcp-rtpengine-utils 11.4.0.0+0~mr11.4.0.0 all scripts and Perl modules for NGCP rtpengine root@pisip:~# sudo dpkg -l | grep bencode ii libbencode-perl 1.501-1.1 all Perl module for BitTorrent serialisation format root@pisip:~# uname -a Linux ... 6.1.25-v8+ #1647 SMP PREEMPT Wed Apr 26 17:39:08 BST 2023 aarch64 GNU/Linux root@pisip:~# cat /etc/issue Raspbian GNU/Linux 11 \n \l ```

Kamailio crashes on startup, only when rtpengine module is loaded and rtp proxies are queried: ``` GNU gdb (Raspbian 10.1-1.7) 10.1.90.20210103-git Copyright (C) 2021 Free Software Foundation, Inc.

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
