calm down folks, there's a quick fix. if you're root just do the following:

- nuke everybody off the system now. tell 'em the disk's on fire.
- as root, run the following

# cd /
# /etc/conf/bin/idtune UAREARW 0

run "kconfig", build a new kernel, install it, and then try
running "that program" again. you should get "memory fault".

it worked for me. your mileage may vary.

speaking of bugs, i have a math-intensive program that appears to
crash 386/387 boxes running either dos or unix. under dos it crashes
with various types of math errors or just hangs, under ISC 3.2.2
it just hangs the system. any ideas anybody?
