but i am curious the question : can infer find out all suspecious bugs epsecially mem leak bugs?

任何工具都不能找出所有的可疑bugs。例如，你如何定义C++、或Java/Android中的内存泄露问题，并让工具完全理解？同时，工具也要跟语言版本与时俱进。
除非你使用内存安全的语言，例如像Rust。

No, Infer is underapproximate by nature, which means that it tries to minimize false positives, while potentially having false negatives (missing bugs). Software model checkers aim to not have false negatives, however they often suffer from performance issues in practice.
