fatal exception

fatal exception

(programming, operating system)
A program execution error which is trapped by the operating system and which results in abrupt termination of the program.

It may be possible for the program to catch some such errors, e.g. a floating point underflow; others, such as an invalid memory access (an attempt to write to read-only memory or an attempt to read memory outside of the program's address space), may always cause control to pass to the operating system without allowing the program an opportunity to handle the error. The details depend on the language's run-time system and the operating system.

fatal error

A condition that halts processing due to faulty hardware, program bugs, read errors or other anomalies. If you get a fatal error, you generally cannot recover from it, because the operating system has encountered a condition it cannot resolve. Typically, buggy applications cause fatal errors (fatal exception errors), and the computer locks up. In most cases, all data that you have changed that has not yet been saved to disk is lost.

There is no rule of thumb with fatal errors. You may never get one again, or it may manifest until you fix the problem. If you get a fatal error after just adding a new peripheral or installing a new software package, remove or uninstall it and try again.
