Microsoft Application Verifier

Application Verifier is a runtime verification tool for unmanaged code that assists in quickly finding subtle programming errors that can be extremely difficult to identify with normal application testing.

Application Verifier is designed specifically to detect and help debug memory corruptions and critical security vulnerabilities. It makes it easier to create reliable applications by monitoring an 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, and more). It also includes checks to predict how well the application will perform under Least-privileged User Account operation.
