The detection of dangling references in C++ programs
Richard A. Eyre-Todd · ACM Letters on Programming Languages and Systems · 1993
Thesmart pointeris a programming technique for the C++ language that extends the functionality of the simple pointer. Smart pointers have previously been used to support persistence, distributed objects, reference counting, and garbage collection. This article will show how smart pointers can provide an inexpensive method for detecting dangling pointers to dynamic objects that can be added to any standard C++ implementation.
