Bus error

<processor> A fatal failure in the execution of a machine language instruction resulting from the processor detecting an anomalous condition on its bus.

Such conditions include invalid address alignment (accessing a multi-byte number at an odd address), accessing a physical address that does not correspond to any device, or some other device-specific hardware error.

A bus error triggers a processor-level exception which Unix translates into a "SIGBUS" signal which, if not caught, will terminate the current process.
