I am developing a video conferencing system (see my other thread), and I am having some trouble with memory leaks in the unmanaged heap. I think it's related to directshow, but the tools I've tried (ANTS and the SciTech memory profiler) do nothing to help find problems in the unmanaged heap. I'm doing everything I can to free memory that's being allocated, but I'm obviously missing something.
I'm looking for other suggestions of tools to use to try to find the leak.
