Question

My program eventually consumes all ram and crashes… looking through the code, I can’t find anything that stands out that would do this.

Answer 1

Could you modify the code to use the debug version of malloc and free? If yes, check _malloc_dbg and _free_dbg.

(You could write own new and delete operators based on these functions.)

As I remember VS 6.0 has no _realloc_dbg.

#ifdef _DEBUG
#define _CRTDBG_MAP_ALLOC 1
#include <Crtdbg.h>
#define malloc(size) _malloc_dbg(size,_CLIENT_BLOCK,__FILE__,__LINE__)
#define free(addr) _free_dbg(addr,_CLIENT_BLOCK)
#endif
