I uncovered a segfault when no home proxy servers are present. I boiled down my configuration to an easily reproducible test case, and made a Docker image to test: https://github.com/normelton/freeradius-crash/tree/main/raddb I have a dummy eduroam server configured at the bottom of proxy.conf and my sites-enabled/default file simply proxies all requests to that server. Otherwise pretty much everything is right out of the default config. Using radclient, my first request is proxied to example.org, which obviously doesn't respond. Eventually the home server is marked dead. Then I send a second request, and freeradius crashes. I'll include the complete debug output below. Here's the mystery ... this is reproducible in 3.0.20, but is seemingly fixed in 3.0.21. I reviewed the release notes for 3.0.21, and don't see anything obviously related. Can anyone confirm this was actually fixed, versus something that might reappear one day? If it were a minor bug, I probably wouldn't care. But a segfault is worth a little more digging. Thanks!
