lubosures commented 1 year ago

Was using rtpproxy for months, building from master branch. Successfully running master branch built on Oct 17, 2022. Built a new version on Feb 9,2023. The code barely survives few calls and segfaults with this backtrace:

(gdb) bt

#5  0x00007f28a2287a2f in clone () from /lib/x86_64-linux-gnu/libc.so.6

The crashes are frequent and consistent, the stack looks the same all the time.

Lubos, thank you for your report. Looks like one of the members has not been initialized properly. Please check the revision 9169c94b or later and see if it helps.

Everything works like a charm again. Kudos for quick investigation and resolution of the problem.
