This paper describes our generic framework for detecting termination of programs handling infinite and complex data domains, such as pointer structures. The framework is based on a counterexample-driven abstraction refinement loop. We have instantiated the framework for programs handling tree-like data structures, which allowed us to prove automatically termination of programs such as the depth-first tree traversal, the Deutsch-Schorr-Waite tree traversal, or the linking leaves algorithm.
