To remember where allocations and deallocations occured paul nettle redefine new and delete like this:
// ---------------------------------------------------------------------------------------------------------------------------------
// Variations of global operators new & delete
// ---------------------------------------------------------------------------------------------------------------------------------
void *operator new(size_t reportedSize);
void *operator new[](size_t reportedSize);
void *operator new(size_t reportedSize, const char *sourceFile, int sourceLine);
void *operator new[](size_t reportedSize, const char *sourceFile, int sourceLine);
void operator delete(void *reportedAddress);
void operator delete[](void *reportedAddress);
#endif // _H_MMGR
// ---------------------------------------------------------------------------------------------------------------------------------
// Macros -- "Kids, please don't try this at home. We're trained professionals here." :)
// ---------------------------------------------------------------------------------------------------------------------------------
#include "nommgr.h"
#define new (m_setOwner (__FILE__,__LINE__,__FUNCTION__),false) ? NULL : new
#define delete (m_setOwner (__FILE__,__LINE__,__FUNCTION__),false) ? m_setOwner("",0,"") : delete
#define malloc(sz) m_allocator (__FILE__,__LINE__,__FUNCTION__,m_alloc_malloc,sz)
#define calloc(sz) m_allocator (__FILE__,__LINE__,__FUNCTION__,m_alloc_calloc,sz)
#define realloc(ptr,sz) m_reallocator(__FILE__,__LINE__,__FUNCTION__,m_alloc_realloc,sz,ptr)
#define free(ptr) m_deallocator(__FILE__,__LINE__,__FUNCTION__,m_alloc_free,ptr)
However, in C++11 you can delete constructors like this:
class TestClass
{
public:
TestClass() = delete; //Breaks the memory tracker!
TestClass(int i) { }
virtual ~TestClass() { cout << "Destructor called." << endl; }
};
Any idea how to modify the memory tracker to work with C++11? Wasn't it pretty damn stupid to choose "delete" for deleting constructors when it is already a keyword for freeing memory?
