--- Comment #5 from John Grafton <john.graf...@runbox.com> --- (In reply to Maarten de Vries from comment #4) Ah, the core file doesn't have symbols (of course, it's a release build). That makes it difficult to figure out what's going on. If you're up for it, you can compile ntpd with debugging symbols and execute it on your 12.4-RELEASE system. This should produce a core file that may point to what's failing. Here's a simple procedure: If you didn't install src, download src.txz from: https://download.freebsd.org/ftp/releases/amd64/amd64/12.4-RELEASE/src.txz untar it in /usr/src: tar -xvC / -f src.txz Check /usr/src/UPDATING and verify the first entry says: 20221205: 12.4-RELEASE. compile ntpd: cd /usr/src/usr.sbin/ntp make execute ntpd with debugging symbols: /usr/obj/usr/src/amd64.amd64/usr.sbin/ntp/ntpd/ntpd -n debug the core file: lldb --core ntpd.core /usr/obj/usr/src/amd64.amd64/usr.sbin/ntp/ntpd/ntpd -- You are receiving this mail because: You are the assignee for the bug.
