We address the verification problem of programs manipulatingone-selector linked data structures. We propose a new automatedapproach for checking safety and termination for these programs. Ourapproach is based on using counter automata as accurate abstractmodels: control states correspond to abstract heap graphs where listsegments without sharing are collapsed, and counters are used to keeptrack of the number of elements in these segments. This allows to applyautomatic analysis techniques and tools for counter automata in orderto verify list programs. We show the effectiveness of our approach, inparticular by verifying automatically termination of some sortingprograms.
