Thanks, this makes the problem clear.

>2. Only found in /usr/bin/sh and /sbin/sh shells.

You forgot to mention that you have PHCO_37286 or PHCO_37177.

>Once the shell process is created, no changes in UNIX95 will correct the problem.

That's right. The shell is looking at its environment and not the environment of the shell user.

Any reason you don't rewrite your test expression in a rational manner, that doesn't use naked strings without a prefix or infix operator:
[ -z 23 -o -n "" ]

In any case, this is a bug in the above two patches for the fix to QXCR1000750268 and you should contact the Response Center. You can mention my name, as to the actual problem.
