Actually, you can control this behaviour with the uac (1) command on
FreeBSD/alpha. 'uac -s' causes unaligned access errors to result in a
SIGBUS being delivered to the parent and its future descendants.
You can also enable/disable printing of errors, etc.  Really handy
when you're using a ghostscript not built w/Compaq C.

Also, Tru64 has a similar command with the same name and different syntax.
