             Summary: segfault in pj_sockaddr_in_set_str_addr
                 Key: ASTERISK-27170
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27170
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: PBX/General
    Affects Versions: 13.16.0
         Environment: 64bit linux musl 1.1.15
            Reporter: nappsoft


>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 (Phone for the NOTIFY OK) -> OK (Phone for the NOTIFY Trying)

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?
