Abstract: Disclosed are typestate and lifetime dependency analysis methods for identifying bugs in C++ programs. Disclosed are an abstract representation (ARC++) that models C++ objects and which makes object creation/destruction, usage, lifetime and pointer operations explicit in the abstract model thereby providing a basis for static analysis on the C++ program. Also disclosed is a lifetime dependency analysis that tracks implied dependency relationships between lifetimes of objects, to capture an effective high-level abstraction for issues involving temporary objects and internal buffers, and subsequently used in the static analysis that supports typestate checking for the C++ program. Finally disclosed a framework that automatically genarates ARC++ representations from C++ programs and performs typestate checking to detect bugs that are specified as typestate automata over ARC++ representations.
