A segmentation fault (often shortened to segfault) or bus error is generally an attempt to access memory that the CPU cannot physically address. It occurs when the hardware notifies a Unix-like operating system about a memory access violation. Then the OS kernel 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.
