Subj : trouble with combination of "for/in" and "with" block

Hi,
I use JSRef 1.5r6a and encounter the following problem:
an object from outer scope ("i" in the example below) is being
modified by a "for...in" iteration when it is placed inside a "with"
block.

Older JSRef (1.4?) used to run the same code without the problem, 
and so does WScript/CScript.
Also, there is NO problem if ANY condition listed below is true: 
A. if "with" block is absent
B. if "for( ; ; )" is used instead of "for...in"
C. if object with same name as object in question appears somewhere
else in the inner scope (of function "f()")

I believe it is a bug, right? I did not find a test case 
that covers my set of conditions.

I understand my case is very specific, and I totally agree
that "with" statement is a poor practice to begin with. 
But this case that I have is present in an old code 
that I have running at a customer site. :( 

Is it possible to use some settings/switches to re-compile
the JSRef to remedy this? Or does it have to be a fix?
Please help if possible. Thanks!
