Abstract

We describe techniques which relate to bi-directional, in particular backwards, debugging of computer programs. Thus we describe identifying processes with shared memory access, such as threads or multicore processes, by arranging process (thread) memory ownership to deliberate provoke memory page faults to identify and handle concurrent memory access by multiple threads in such a manner as to enable deterministic replay, and hence backwards debugging.
