I wish you were right, this would solve the problem. but according
to zsh man page :
In sh and ksh compatibility modes
The usual zsh startup/shutdown scripts are not executed.
I just tried to put ": > /tmp/zsh.$$" in /etc/zsh/zshenv and run ksh (the
symlink to zsh)... No file were present in /tmp :-(

No doubt. But as I wrote in reply to Clint message, we all have different
idea of what a 'ksh' should be.
I originally sent the report because I *feel* a trap on ERR was such a
basic thing that any ksh should implement it.
I learned life is not that simple, and one OS uses SIGERR just to make life
harder for every one.
Now, unless you have another workaround, it seems there is no
simple way to solve this.
I can only hope Debian maintainers will agree with me, and perhaps some
zsh-workers too ;-)

Thanks for the info.
Going back to real life,
