Crash in std string functions - gcc 3.4.5

["Bhawalkar, Shreerang" <Shreerang dot Bhawalkar at ca dot com>]

I have a multi-threaded application that I build using gcc 3.2.2 on RHAS
3.0. When I try to execute this application on a RHAS 4.0 machine (that
has gcc 3.4.5 installed), I get a number of crashes, most of them in
std::string functions. Surprisingly most of the crashes get resolved
when I do a reserve() on the culprit std::string object. However
resolving one crash leads to another and it seems that I need a patch to
fix this problem rather than making large scale changes in my code.
Given below is a sample of 2 core dumps that I got. Please note that
this application runs fine on RHAS 3.0. It is only when I run the
aplication in RHAS 4.0 that hell breaks loose.

Please let me know, where I can find the patch to fix this problem.
