Application Verifier

What is Application Verifier?

Application Verifier is a runtime verification tool for native code that assists in finding subtle programming errors that can be difficult to identify with normal application testing. Application Verifier is designed specifically to detect and help debug memory corruptions and critical security vulnerabilities.
This is achieved by monitoring a native application's interaction with the Windows operating system, profiling its use of objects, the registry, the file system, and Win32 APIs (including heaps, handles, locks, etc), and indicating issues when and where they are discovered.
