RE: Crash while using transform method on MacOSX - Genric STL pro blem

[Sanjay Arora]

I tried to narrow down the problem and segregated the smallest code snippet
which causes the problem. I am attaching my version here.
The code crashes while appling the += operator in STL code.
The following code works fine on Windows platform but crashes on MacOSX with
code warrior 8.3 with MSL STL.

Could any one suggest me what wrong in here.

Regards
Sanjay
