hmm... I enabled tpsDecode on an Analog system and I am not able to get it to SEGFAULT, which is weird. It probably means that the decoded messages are triggering it since I am not near any channels that have this. I haven't touched any relevant code recently though.

:smirk: I'm not near anything that uses tps either afaict. I just enable all the decoders on analog channels that are multiagency use in case someone does :-)

any idea how I might get you a more useful backtrace?

I can look into it a little deeper tomorrow night. Can you record some audio from the system you were monitoring when this happened?

FDNY uses TPS if you're anywhere near NYC.

Going by assert_fail in the output, this seems likely related to https://github.com/robotastic/trunk-recorder/issues/780 and can be reproduced and found more quickly in testing with https://github.com/robotastic/trunk-recorder/pull/793

most assert fixes are complete at this point so I'm going to close this until I reproduce
