N2 - Witch 3 is a new validator of violation witnesses in the witness format 2.0. Note that our previous tool, Symbiotic-Witch 2, can validate only violation witnesses in the old GraphML format. Witch 3 validates witnesses of reachability of an error function, overflows, and invalid dereferences and deallocations. Similarly to Symbiotic-Witch 2, the tool is based on symbolic execution and uses parts of the Symbiotic framework. Support of the witness format 2.0 in Witch 3 includes features not supported by Symbiotic-Witch 2, such as constraints on the program variables and function return values, specifying statements by column, and providing the concrete statement in which the violation occurs. These additional features can further restrict the explored state space, and, more importantly, allow for much more precise validation.
