Recent 14-STABLE amd64
FreeBSD 14.1-STABLE #0 stable/14-n268159-60f78f8ed14d: Tue Jul 16 19:25:41
AEST 2024

No segfault if I specify -j to restrict dispaly to one of the jails, only if I
specify -j0 or omit -j. This is my third build of 14-STABLE (beginning early
May) and all of them have done the same. Same vintage 14-STABLE on i386 is
fine. I only have the two systems running FreeBSD.
