 * __verbose_terminate_handler()
 *
 * This is the function that is called when an uncaught C++
 * exception is encountered. The default version within the C++
 * library prints the name of the uncaught exception, but to do so
 * it must demangle its name - which causes a large amount of code
 * to be pulled in. The below minimal implementation can reduce
 * code size noticeably. Note that this function should not return.
