Static Analysis is widely recognized as a fundamental tool for program verification, bug detection, compiler optimization, program understanding, and software maintenance. The series of Static Analysis Symposia has served as the primary venue for the presentation of theoretical, practical, and application advances in the area. The 25th Static Analysis Symposium, SAS 2018, will be held in Freiburg, Germany. Previous symposia were held in New York, Edinburgh, Saint-Malo, Munich, Seattle, Deauville, Venice, Perpignan, Los Angeles, Valencia, Kongens Lyngby, Seoul, London, Verona, San Diego, Madrid, Paris, Santa Barbara, Pisa, Aachen, Glasgow, and Namur. The proceedings of the conference will be published in the Advanced Research in Computing and Software Science (ARCoSS) subline of the Springer Lecture Notes in Computer Science (LNCS) series.
