A fatal error is usually distinguished from a fatal system error (colloquially referred to in the MS Windows operating systems by the error message it produces as a "blue screen of death"). A fatal error occurs typically in any of the following cases:.

In some systems, such as Mac OS X and Microsoft Windows, a fatal error causes the operating system to create a log entry or to save an image (core dump) of the process.
