The simplest option is to enable Page Heap Mode but it does require plenty of spare address space (link with /LARGEADDRESSAWARE if it's a 32-bit program to double available address space when run on 64-bit Windows).
You could also try http://www.drmemory.org/ but it's not so easy to use.

Page Heap puts each allocation on its own 4-KB page, with the allocated memory aligned to the end of the page. Therefore if you overrun the buffer you will touch the next page. Page Heap ensures that the next page will be unmapped memory so you get a guaranteed access violation at the exact moment that you overrun the buffer.
