A segmentation fault (often shortened to segfault), bus error or access violation is generally an attempt to access memory that the CPU cannot physically address. It occurs when the hardware notifies an operating system about a memory access violation. The OS kernel then sends a signal to the process which caused the exception. By default, the process receiving the signal dumps core and terminates. The default signal handler can also be overridden to customize how the signal is handled.

Famous quotes containing the word fault:
“All the satires of the stage should be viewed without discomfort. They are public mirrors, where we are never to admit that we see ourselves; one admits to a fault when one is scandalized by its censure.”
—Molière [Jean Baptiste Poquelin] (1622–1673)
