Hi,
we found a regression in ksh. Exporting a variable affects its attributes:
$ typeset -Z2 foo=3
$ echo $foo
03
$ typeset -p foo
typeset -Z 2 -R 2 foo=03
$ export foo
$ echo $foo
3
$ typeset -p foo
typeset -x -Z 1 -R 1 foo=3
last working version is 2009-06-30, first broken version is 2009-09-08.
Let me know if you need more information.
Michal
