dangling pointer-bugs fixing

[mark Antony]

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?

That is because they are very hard bugs to find and fix.

I would suggest

1. If you are using pointers when you delete the data the pointed to set the pointers value back to NULL. This way rather than getting data corruption you will (hopefully get NULL pointer exceptions that you can find and fix)

or

2. Rather than pointers use handles, handles are smart pointers that only delete the data once everyone has finished using it Handle Classes: The Smart Pointer
