What are some good tools for measuring memory allocations on Windows?

Question

I have an application that keeps using up more and more memory as time goes by (while actively running), but there are no leaks. So I know the program isn't doing something totally wrong, which would be easy to find.

Instead I want to track allocations so I can start tracking down the issue, and on a Mac I'd use Instruments, which gives a detailed profile of what objects have been allocated, and by whom, but on Windows what would I use?

Currently I'm working with C/C++ on Windows XP, using VS2005. So any tools for this setup would be great, and hopefully tools that are free or at least provide a few weeks of trial, because it'll take a while to complete any purchase (corporate stuff) if necessary, and I have deadlines.

Thanks!

Edit: I'm using VLD, so I know the program has no Leaks, but it seems to be hogging more memory than needed, and not returning it, so I need to track allocations, not leaks.

Memory validator would be ideal for you. http://www.softwareverify.com/cpp/memory/index.html
