Subsequent cleanup code, typically in a distant part of the function, references the NULL pointer while cleaning up from a more likely error.A pointer and the pointed-to data are both checked for NULL correctly, but a debug/warning message that is printed uses the pointer that might be NULL...

After a lot of reading, I have concluded that I am dereferencing a Null Pointer and then trying to use it after this. However, nowhere in my code do I overtly set a pointer to 0 or NULL. I've read that return values from methods (particularly if using "if" statements) can set poi...

Before you derefrence a pointer, you could check if it is a null pointer with something like: if (myPointer != nullptr) /*do something with it*/ ; That should help you avoid the problem and hopefully locate it so that you can prevent trying to use a nullpointer. ...

I have unintentionally raised a large debate recently concerning the question if it is legal in C/C++ to use the &P->m_foo expression with P being a null pointer. The programmers' community divided into two camps. The first claimed with confidence that it wasn't legal while the others ...
