Странный кодю Ибо основоположник делал это так
void* operator new(size_t);
void* operator new[](size_t);

Хмм
а вся беда в define
берем код
#define DEBUG_NEW new(__LINE__)
#define new DEBUG_NEW

void* operator new(size_t size, int line)
{
void *ptr = (void *)malloc(size);

data.address = (unsigned long)ptr;
data.line = line;
data.size = size;
mySpy.AddToList(data);

return (ptr);
};//new(unsigned int size)

int main()
{
char* c_ptr;
c_ptr = new(char);
delete c_ptr;
c_ptr = new char;
delete c_ptr;
}
после препроцессора
void* operator new(4)(size_t size, int line)
{
void *ptr = (void *)malloc(size);

data.address = (unsigned long)ptr;
data.line = line;
data.size = size;
mySpy.AddToList(data);

return (ptr);
};

int main()
{
char* c_ptr;
c_ptr = new(19)(char);
delete c_ptr;
c_ptr = new(21) char;
delete c_ptr;
}
