c++的set_unexpected不起作用

代码是从：http://www.cplusplus.com/referen ... /?kw=set_unexpected找的

 

// set_unexpected example

#include <iostream>       // std::cerr

#include <exception>      // std::set_unexpected



void myunexpected() {

        std::cerr << "unexpected called\n";

        throw 0;     // throws int (in exception-specification)

}



void myfunction() throw (int) {

        throw 'x';   // throws char (not in exception-specification)

}



int main(void) {

        std::set_unexpected(myunexpected);

        try {

                myfunction();

        }

        catch (int) { std::cerr << "caught int\n"; }

        catch (...) { std::cerr << "caught some other exception type\n"; }

        return 0;

}

在windows下编译运行之后myunexpected没有被调用
ubuntu下试了一下，没有问题，求解
