We have Visual Studio C++ .NET 2003.

Question: Quite a few years ago, there were bugs in the Dinkumware STL
libraries distributed by MS as part of VS 5.0 and 6.0. The bugs exhibited
themselves as heap corruption on multiprocessor systems and that gave us
major headaches for over a year. The patches seemed to help some, but
over time we ripped out most all the STL references.

From what I was told at the time was there was licensing issues with
Dinkumware that couldn't be resolved, so the STL fixes were never
distribute by MS. You could only get the fixes here:

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

We've started using STL again assuming all of that has been fixed by 2003,
and suddenly we're once again seeing crashes in RtlFreeHeap again,
numerous times a day.

Do we need STL patches again?

No, all of the patches became part of the main distribution with VC7. If
you're seeing problems again, there's probably a lurking problem in your
code that was responsible for part of the problems you saw with VC6.
