    Hi,
    I find very difficult to fix the dangling pointer bug occurred in my new open source office application developed in C++ language. I need some information to resolve this bug?

    Hi,
    Usually dangling pointers arises when an object is deleted or deallocated , without modifying the value of the pointer, so that the pointer still points to the memory location of the deallocated memory. As the system may reallocate the previously freed memory to another process, if the original program then dereferences the (now) dangling pointer, unpredictable behavior may result, as the memory may now contain completely different data. This is especially the case if the program writes data to memory pointed by a dangling pointer, as silent corruption of unrelated data may result, leading to subtle bugs that can be extremely difficult to find, or cause segmentation faults. You didn’t mention the code for resolving the bug.
