I just tested ksh 93u+ 2012-02-02 and although the two test test scripts I
posted earlier don't cause ksh to segfault the following slightly different
script does.
$ cat b
function g { IFS= ; }
function f { typeset IFS ; (g) ; : $V ; }
f
f
$ ksh b
Segmentation fault
$ ksh --version
version sh (AT&T Research) 93u+ 2012-02-02
Running Ubuntu 11.10.
