Abstract
: The incorrect use of pointers is one of the most common source of bugs in imperative languages. In this context, any kind of static code checking capable of detecting potential bugs at compile time is welcome. This paper presents a static debugging technique for the detection of incorrect accesses to memory (dereferences of invalid pointers). The analysed language is a subset of C. The tool is based on a static analyser extended with assertions inserted in the body of the program. Assertions are of two kinds: ffl static assertions automatically verified by the analyser, ffl dynamic assertions treated as assumptions by the analyser. The technique deals with dynamically allocated data structures and it is accurate enough to handle circular structures.
