Hello pjsip developers, Any update on this? Did you create a trac ticket for this issue? Br, /Håkan From: Håkan Berg
Hello, I believe I’ve found a null pointer dereference in pjsua, when terminating a call while trying to connect to a turn server that does not respond. To reproduce: Compile pjsip for linux x86_64 (./configure && make && cd pjsip-apps/bin) Start pjsua with turn enabled, using a bogus ip to represent a turn server that does not currently respond, and call any ip: gdb --args ./pjsua-x86_64-unknown-linux-gnu --use-ice --use-turn --turn-srv 8.8.8.8:12345 --turn-user na --turn-passwd na --playback-dev=1 --capture-dev=1 --id
sip:localhost --app-log-level=6 --no-cli-console --duration=10 press m, enter sip:4.4.4.4 press h ... Program received signal SIGSEGV, Segmentation fault. 0x0000000000429047 in pjsua_call_hangup (call_id=2, code=0, reason=0x0,
