ISO/IEC 14882:1998(E):

"If no matching handler is found in a program,
 the function terminate() is called; whether or
 not the stack is unwound before this call to
 terminate() is implementation-defined"

"In the situation where no matching handler is found,
 it is implementation-defined whether or not the stack
 is unwound before terminate() is called."

"18.6.3 Abnormal termination Type terminate_handler

 typedef void (*terminate_handler)();

 1 The type of a handler function to be called by terminate()
   when terminating exception processing.

 2 Required behavior: A terminate_handler shall terminate
   execution of the program without returning to the caller.

 3 Default behavior: The implementation's default
   terminate_handler calls abort()."
