That's bad. If you use native FreeBSD ktrace, then you should see
only using native libc. And if native ktrace tries to use /compat...
that's too bad. It shouldn't.

For tracing linux libs one sjould use linux_kdump. But that's another
story.

Well, that may be the curprit. Yur should never use ldconfig until
you *know* what you do. For linux libs only linux ldconfig is used
and with chroot (-r /compat/linux).

You shoudn't see it with native ktrace.

Seems that you rewrote your linux(?) ldconfig database. It's not so hard
to restore. Remove /compat/linux/etc/ld.so.cache and rebuild it by
"sudo /compat/linux/sbin/ldconfig -r /compat/linux".
