*** (#1 of 2): 2010-10-08 14:00:59 GMT+00:00 <User 1-9HOB9N>
I don't see this on a system running build 150.

=== *Public Comments* ========================================================
Sent a mail to the submitter asking which build he saw this problem on.
Haven't heard from him.
I am closing this CR as not reproducible.
As AlanC pointed out build 134 was the last build community have access
to, so I suggest, please check if you see this issue with 134, if so
discuss with ksh93 community to figure which CR fixed this issue
and make those chanes in your workpace.
