Like this?

michael@feivel:~$ export MALLOC_CHECK_=2
michael@feivel:~$ export MALLOC_PERTURB_=$(($RANDOM % 255 + 1))
michael@feivel:~$ column -ets, < foo > bar
column: line too long

No segfault whatsoever.

BTW the "line too long" message disappears if I add a final CR but no still no
segfault. I also tried on a Wheezy i386 system without getting it to segfault.

What kernel do you run on? The original report talked about 3.5. I'm on our
Wheezy 3.2 kernel. Maybe that makes a difference.
