Post your code, the diagram you posted is not very helpful to find the problem in your program. My guess is that the pointer you used was not initialized to a specific address before dereferencing it. For example
int k = 123; // original integer
int* p = &k; // initialize a pointer
int q = *p; // dereference the pointer
