Center node: "understanding counterexamples for relational properties with dibugger"
  Abstract: Software verification is a tedious process that involves the analysis of multiple failed verification#R##N#attempts, and adjustments of the program or specification. This is especially the case for complex#R##N#requirements, e.g., regarding security or fairness, when one needs to compare multiple related runs#R##N#of the same software. Verification tools often provide counterexamples consisting of program inputs#R##N#when a proof attempt fails, however it is often not clear why the reported counterexample leads to#R##N#a violation of the checked property. In this paper, we enhance this aspect of the software#R##N#verification process by providing \emph{DIbugger}, a tool for analyzing counterexamples of relational#R##N#properties, allowing the user to debug multiple related programs simultaneously.
