If you’re running in Docker and getting segfaults this thread shows how I enabled the required reporting makeopts in a Docker build: Non-interactively enabling menuselect debug options
Might be useful to you. The segfault I experienced was in testing a new container so I was able to shell in and process the coredump by hand. I have persistent storage in my Asterisk container for things like the voicemail spool, I assume the core could be configured to dump there for post-processing but I haven’t set that up yet.
