Finding where memory was last freed?

Answer 1

Short answer: no.

What you need is a debug malloc. I don't keep up with Windows any longer but there are several about, including this free one.

Update

Looks like Visual Studio C has a built in version. See here

When the application is linked with a debug version of the C run-time libraries, malloc resolves to _malloc_dbg. For more information about how the heap is managed during the debugging process, see The CRT Debug Heap.

... and see here for _malloc_dbg.
