have finally tracked down the source by using the Microsoft tool umdh

a small code snippet. Hopefully I can post enough information here to
make sense to folks.

BTW, I am compiling with Visual C++ 6.0.

Have you applied the STL patches available from

https://www.dinkumware.com/vc_fixes.html

??

If not, you should. Pay particular attention to the fixes to <xstring>

-cd

Ahhhh, thanks. I needed to make std::string thread-safe. There is
more information about this problem here:

I still have one more leak that has something to do with std::string.
I am surprised that the dinkumware fixes did not address this leak as
well. Here is the output from umdh for that one:

Follow up: the first leak is not present in VS 2005, as expected. The
second leak is. Based on what I've gleaned from other posts in this
group, it is a safe bet that I'm at fault for that one, so I'll take a
closer look at the code.

Thanks again,
