Heap corruption: What could the cause be?

Question

I am investigating a crash due to heap corruption. As this issue is non-trivial and involves analyzing the stack and dump results, I have decided to do a code review of file

Answer 1

There are products that will observe the memory allocations and deallocations, and produce a report on anomalies. Last I used one, they weren't cheap, but I don't know what the situation is right now. However, finding stuff for VC++ 6 might be a problem.

Remember that you're liable to be getting heap corruption a lot more often than you're going to crash, so be attentive to the problem reports, and fix all heap corruption.

I'd suggest using std::tr1::smart_ptr<> instead of raw pointers everywhere, but I'm not sure VC++ 6 is going to support that.

Why are you still on VC++ 6? Would it be practical to upgrade? The tools are better with the more recent versions, and they fully support smart pointers.
