>Description:
Any linux binary causes a seg fault.  It appears all the binaries in /compat/linux/bin cause a seg fault.

asus# /compat/linux/bin/echo "asdf on FreeBSD"
Segmentation fault (core dumped)

I think I am missing something, but, what?
What can I do to help resolve this?

asus# kldstat
Id Refs Address    Size     Name
 1   13 0xc0400000 bc324c   kernel
 2    1 0xc7505000 68000    radeon.ko
 3    1 0xc7572000 14000    drm.ko
 4    1 0xc7d83000 26000    linux.ko

asus# mount
/dev/ad8s1a on / (ufs, local)
devfs on /dev (devfs, local, multilabel)
/dev/ad8s1d on /usr (ufs, local, soft-updates)
/dev/ad8s1g on /usr/home (ufs, local, soft-updates)
/dev/ad8s1e on /usr/local (ufs, local, soft-updates)
/dev/ad8s1f on /var (ufs, local, soft-updates)
linprocfs on /usr/compat/linux/proc (linprocfs, local)

I expected this to be funny, but, I include it anyway
asus# gdb -c echo.core
