See lazarus: components/codetools/memcheck.pas
The include file (memcheck_laz.inc) contains the added features:
procedure CheckHeap(const txt: ansistring);
procedure CheckHeapWrtMemCnt(const txt: ansistring);
procedure WriteGetMemCount(const txt: ansistring);
function MemCheck_getmem_cnt: longint;
function MemCheck_freemem_cnt: longint;
function MemCheck_getmem_size: longint;
function MemCheck_freemem_size: longint;
function MemCheck_getmem8_size: longint;
function MemCheck_freemem8_size: longint;
You may want to change the longints to int64.
