代码是从：找的

 

// set_unexpected example#include 
     
             // std::cerr#include 
      
             // std::set_unexpectedvoid 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
