C++ memory detection tool based on dynamic instrumentation

Abstract

C++ language has the characteristics of flexible programming, high execution efficiency, but there are also a large number of undefined behavior, which is easy to cause security risks. In this paper, focus on the memory-use error in C++ program, designed and implemented a memory check tools named MemDetect, based on dynamic instrumentation platform, which is platform-cross, efficiency and accuracy. MemDetect can detect memory leaks, cross-border access memory and memory does not match the release problems effectively, the validity and efficiency of MemDetect are proved by comparing with other detection tools.
