I honestly can't remember what happened with this line of work - but I'm looking at incorporating these changes now @jackylai0. I'm planning on adding some other features soon and wanted a good starting point. Branch merge_jackylais_work.

"I decided to ditch the changes to make the profiler not use malloc for now. They didn't compile."

@lukedodd You mean HeapAllocator? It is based on VS2010 std::allocator and modify to use HeapAlloc/HeapFree instead. Maybe std::allocator changes is too extensive and have to re-adapted for VS2019.

@lukedodd Please check my latest commits. I merged your branch again and fixed various bugs (including HeapAllocator compile error).
