The PR has everything in it. Yes, simply invoking from another
(interactive) shell does not cause crash, only under a particular
situation.
To reiterate & rephrase, edit "~/.profile" to have ...
ENV="${HOME}/.kshrc-segfault"
export ENV
rm -f initially-nonexistent-file
> initially-nonexistent-file &
exec $0
... and, edit "~/.kshrc-segfault" to have only ...
set -o notify
... then in an interactive shell (tcsh, sh, bash, ksh93), type the
following in order ...
ksh93 # run ksh93 under another shell
. ~/.profile # source ~/.profile under ksh93
...which ends in a crash, if the first time does not produce crash,
2d time sure does. Following was also tried, in order, just in
case, resulting in the same...
# Change tcsh to sh, bash, or even ksh93 (in which case, no need for
# the 2d step)
xterm -e tcsh # 1
ksh93 # 2
. ~/.profile # 3
