Might need to flip kern.sugid_coredump for a minute and see if you can gather some more context from a coredump.Well, yes (it's somewhat unusual) and no (I think it's expected behavior here): It's not unusual for a program to explicitly abort() when a setgroups() call failed, though: if I was the programmer who wanted to drop privileges and failed, showing some error message and abort() as soon as possible would be a reasonable choice (IMHO) because I wouldn't have a lot of other remedies, so to me it sounded reasonable here, especially when Alexander saw some missing system calls earlier.
COMPAT_FREEBSD14 makes a huge difference. Seems you find the issue. We should change the UPDATING part and tell to use COMPAT_FREEBSD14 until all the 3rd party stuff is updated/recompiled.
