At TACAS 2019, we published a decision procedure for the entailment problem for symbolic-heap separation logic with inductive definitions of bounded treewidth based on a novel abstraction we called the profile abstraction. Since then, we have discovered an incompleteness issue with that decision procedure, as well as a generalization of the profile abstraction that fixes the issue. In this article, we give a high-level discussion of the approach of our TACAS paper, identify the reason for its incompleteness, and explain the necessary changes to obtain a complete decision procedure while retaining the same asymptotic complexity. A complementary article with a full formalization of the extended decision procedure is currently under preparation.
