Are there any tools to detect buffer overflow on Visual C++ 6.0?

Question

I've been having crash problems due to heap problems, so I guess a buffer overflow is happening somewhere. How do I detect it?

"heap problems" are far from synonymous with "buffer oberflow" — , Apr 23 '09 at 20:05
They aren't synonyms, certainly, but heap problems are a likely symptom of buffer overruns. — RBerteig, Apr 23 '09 at 20:14

I use Compuware BoundsChecker as a tool for error detection in VC6. It can pick up buffer overruns.

You can also try PageHeap, a tool for windows.

I use Rational Purify for this.

You can use the VC debug heap: http://msdn.microsoft.com/en-us/library/974tc9t1.aspx

Most if not all of the stuff in crtdbg.h is also supported in VC6.

I got good results when simply inserting _heapchk() Windows API function on some places and hunt the error (a access to index -1 to an array in my case).
