The series of Static Analysis S- posia is a forum for the presentation and discussion of advances in the area. This volume contains the papers accepted for presentation at the Ninth - ternational Static Analysis Symposium (SAS 2002), which was held Sept- ber 17-20, 2002 in Madrid, Spain. Previous SAS symposia were held in - ris, France (LNCS 2126), Santa Barbara, CA, USA (LNCS 1824), Venice, Italy (LNCS1694),Pisa,Italy(LNCS1503),Paris,France(LNCS1302),Aachen,G- many (LNCS 1145), Glasgow, UK (LNCS 983), Namur, Belgium (LNCS 864), followingtheinternationalworkshopWSAinPadova,Italy(LNCS724),Bor- aux,France(BigreVol.81-82)andJTASPEFL/WSA,Bordeaux,France(Bigre Vol. 74). In response to the call for papers, 86 contributions were submitted from 12 di?erent countries. Following on-line discussions, the Program Committee met in Madrid on June 22, 2002, and selected 32 papers, basing this choice on their scienti?cqualityandrelevancetothesymposium.Eachpaperwasreviewedbyat leastthreeProgramCommitteemembersorexternalreferees.Inadditiontothe contributed papers, this volume includes abstracts of invited talks by Thomas Reps(UniversityofWisconsin,USA),RobertHall(AT&TLabsResearch,USA), and Javier Esparza (University of Edinburgh, United Kingdom). On behalf of the Program Committee, the Program Chairs would like to thank all the authors who submitted papers and all the external referees for their careful work in the reviewing process. The support of the several funding agencies, listed later in the volume, which provided part of the funds for the organization of the conference is also gratefully acknowledged.
