In particular, the fact there an INVITE request came in with no known formats is ... odd. A pcap along with the backtrace, as well as your {{modules.conf}} would be useful in figuring out what occurred.

Update again.  I just fixed that compile error.

@Private, are you able to recompile and provide the requested information?

I no longer have access to a box with this version. I was scolded for putting Asterisk 12 in production, and decided to follow the advice given. Also, the channel PJSIP is useless until it updates the channel variables, like the regular SIP channel does, i.e., CHANNEL(recvip), etc. It does not. By the way, the CHANNEL() needs a variable with the inbound peer name, if any, and a flag that says if it is registered or not, since a peer does not need to register.

Thanks for the response. I'll go ahead and close it out since you and we can't reproduce.
