A large leak might result in unacceptable response times due to excessive paging. Eventually the application as well as other parts of the operating system will experience failures. Windows will free all memory allocated by the application on process termination, so short-running applications will not affect overall system performance significantly. However, leaks in long-running processes like services or even Explorer plug-ins can greatly impact system reliability and might force the user to reboot Windows in order to make the system usable again.
Applications can allocate memory on their behalf by multiple means. Each type of allocation can result in a leak if not freed after use. Here are some examples of common allocation patterns:. NET Framework 3. Note: the Application Verifier version that ships in Visual Studio is quite dated.

Creating a named synchronization object Event, Semaphore, Mutex, etc without a namespace may complicate running without privilege on some operating systems because the operating system may choose to place the object in a restricted namespace. Creating such an object in a restricted namespace such as the Global namespace requires SeCreateGlobalPrivilege, which is granted only to administrators.
LuaPriv flags both these issues if it detects them. In those cases, the application may change its behavior depending on how much power it thinks the user has. LuaPriv flags API calls that return this information.
An application may attempt to enable a security-relevant privilege such as SeTcbPrivilege or SeSecurityPrivilege prior to performing an operation that requires it. LuaPriv flags attempts to enable security-relevant privileges. You cannot use this method to activate the Storport Verification options. For information, see Storport Verification. Each positive decimal integer represents a verification class.
Multiple classes can be expressed by separating each class id with a space character. The following rule classes IDs are available. These rule classes are intended for specific scenario testing.
