>Description:

Running "jls -n" with or without active jails makes "jls" coredump 

Running "jls" works.
Running "jls -v" works.

pstack -e /usr/sbin/jls jls.core

(core file "jls.core"): /usr/sbin/jls

Also running "jls -j abc" coredumps:

pstack -e /usr/sbin/jls jls.core

Problem is only seen on one out of two FreeBSD 8.1 systems: an Acer Aspire 1410 netbook.

I've also got a Soekris net5501 running FreeBSD-8.1 - this system does not seem to have the problem.

Just a thought - could it be NX/XD related ?
