247986 - Script that worked in V1.6 are now broken in V1.7

Status: VERIFIED DUPLICATE of bug 247987

(Core :: JavaScript Engine, defect)

Description

[Chris Waldron]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705)
Build Identifier: 

I wrote a JavaScript class library supporting class-base inheritance.  Much of 
what is done is by copying property information from the base class into the 
derived class.  This library was working since version 1.4 and continued to 
work for all version until version 1.7

What I'm seeing is that the inheritance is not being carried through as 
expected causing a stack overflow.  I haven't been able to narrow down 
specifically where the discrepancy is occurring but it would appear to me that 
you can find this much faster since you know what in the JavaScript engine 
changed between 1.6 and 1.7

Unfortuately there is no means for me to send you an attachment of the ASP.NET 
application that reproduces can be used for debugging.  Therefore you'll need 
to contact me ([e-mail]) so that I can then send you the repro case.



Reproducible: Always
Steps to Reproduce:
1.  Get the repro zip file from [e-mail]
2.  Build and run the ASP.NET application
3.  Run in version prior to 1.7 -- works
    Run in version 1.7 and later -- fails

Actual Results:  
Stack overflow -- Page is displayed with errors.

Expected Results:  
The application should work like it did in version 1.4 - 1.6

Please contact me -- [e-mail] and I can then send you the repro case
