21.8 Exception handling [support.exception]

21.8.4 Abnormal termination [exception.terminate] terminate [terminate]

[[noreturn]] void terminate() noexcept;

Remarks: Called by the implementation when exception handling must be abandoned for any of several reasons ([except.terminate]). May also be called directly by the program.

Effects: Calls a terminate_­handler function. It is unspecified which terminate_­handler function will be called if an exception is active during a call to set_­terminate. Otherwise calls the current terminate_­handler function. [Note: A default terminate_­handler is always considered a callable handler in this context. end note]
