The road to such success is, however, paved with many failed proof attempts. The message produced by the prover when a proof fails is often obscure, making it very hard to know how to proceed further. The work reported here attempts to help in such cases by providing immediately understandable counterexamples. To this end, it introduces an approach called Counterexample Extraction and Minimization (CEAM). When a proof fails, CEAM turns the counterexample model generated by the prover into a a clearly understandable version; it can in addition simplify the counterex-amples further by minimizing the integer values they contain. We have implemented the CEAM approach as an extension to the AutoProof verifier and demonstrate its application to a collection of examples.","PeriodicalId":178302,"journal":{"name":"2022 IEEE International Symposium on Software Reliability Engineering Workshops (ISSREW)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116672841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When malloc() Never Returns NULL—Reliability as an Illusion 当malloc()永远不会返回null时——可靠性是一种错觉

This validation step is necessary to avoid crashes and undefined behavior. However, in user mode, in modern operating systems (OS), such as Android, FreeBSD, iOS, and macOS, the caller does not have an opportunity to handle the memory allocation failures. This behavioral trait results from the actions of a system component called an out-of-memory (OOM) killer. We identify that the only mainstream OS that, by default, lets applications detect memory allocation failures is Microsoft Windows. The false expectation that an application can handle OOM errors can negatively impact its design. The presence of error-handling code creates an illusion of reliability and is wasteful in terms of lines of code and code size. We describe the current behavior of a sample of popular OSs during low-memory conditions and provide recommendations for engineering practices going forward.","PeriodicalId":178302,"journal":{"name":"2022 IEEE International Symposium on Software Reliability Engineering Workshops (ISSREW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125549254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
