I would assume this is also because of a recursive function filling up
the stack (it segfaults on my Debian 3.0 on a push %edi in malloc()). I
don't know how exploitable this is at all.

Subject: A different bash blues
In relation to the Bash Blues thread, I have something that may be of
interest.
eval `perl -e 'print ":;" x 97500'`
This causes bash to crash too sig 11. I don't know if this means
anything
or not, but who knows, it may be useful to someone else. The number
97500
is most likely a lot higher that it needs to be but I have noticed that
when I have tried this on different machines, it takes slightly
different
amounts of :; to get it to crash.
