Why not just use unit heaptrc?


Quoted from that page:

	The HEAPTRC unit can be used to debug your memory
	allocation/deallocation. It keeps track of the calls to
	getmem/freemem, and, implicitly, of New/Dispose statements.

	When the program exits, or when you request it explicitly. It
	displays the total memory used, and then dumps a list of blocks
	that were allocated but not freed. It also displays where the
	memory was allocated.

	If there are any inconsistencies, such as memory blocks being
	allocated or freed twice, or a memory block that is released
	but with wrong size, this will be displayed also.

	The information that is stored/displayed can be customized using
	some constants.

Works very well.
