FreeBSD emulation seems to be broken on my October 17 kernel; almost
all FreeBSD programs get a bus error and dump core. Is it working for
anyone else? One program that doesn't always core is
/emul/freebsd/sbin/ldconfig. If I run ldconfig -h, it prints the usage
message, but plain ldconfig cores.

Here's a ktrace (of /emul/freebsd/usr/bin/ldd) (hmm... just noticed
that kdump doesn't know about freebsd emulation):
