nappsoft commented on ASTERISK-27170:
-------------------------------------

Well then we need to let this unfixed for the moment... While DONT_OPTIMIZE (currently the DONT_OPTIMIZE version is running) isn't a problem at all, there are tons of compilation issues with MALLOC_DEBUG for which we currently do not have time to investigate. For BETTER_BACKTRACES our distribution does currently not have libbfd (usually it takes some time to integrate new libs when cross-compiling) and there are some cross-compile issues with bundled pjproject as well, at least it was like that last time.

> From time to time asterisk crashes in pj_sockaddr_i_set_str_add. The asterisk version we use is 13.16.0 with some stability patches that flew into 13.17.0 (we will update to 13.17.0 soon). But we already had the same crashes with unpatched 13.16.0 versions and with older versions as well.
> According to the sip traces the last thing that happened was a sip transfer. The messageflow was:
> REFER (Phone) -> 202 Accepted (PBX) -> NOTIFY Trying (PBX) -> NOTIFY OK (PBX) -> BYE (Phone) - > OK (PBX for the BYE message) -> OK (Phone for the NOTIFY Trying) -> OK (Phone for the NOTIFY OK)
> As these are embedded systems with limited resources it's always difficult to make crash dumps there or to run asterisk in gdb... I'll try to get some complete backtraces in the future, but maybe somebody has an idea based on the described scenario. => maybe there is a race condition when the Phone sends OK messages for the NOTIFY messages after that the phone has already sent a BYE for the same call?
