我的机器上的std :: promise是否损坏(使用g ++-mp)? [英] Is std::promise broken on my machine (using g++-mp)?

问题描述

此代码有效，还是我的编译器损坏了?

Is this code valid, or is my compiler broken?

#include <future>
#include <iostream>

int main() {
   std::cout << "doing the test" << std::endl;
   std::promise<bool> mypromise;
   std::future<bool> myfuture = mypromise.get_future();
   mypromise.set_value(true);
   bool result = myfuture.get();
   std::cout << "success, result is " << result << std::endl;
   return 0;
}

这是输出:

$ g++-mp-4.8 -std=c++11 test.cpp
$ ./a.out
doing the test
Segmentation fault: 11
$ 

我正在使用g ++-mp-4.8，它是macports中的gcc 4.8.

I'm using g++-mp-4.8, which is the gcc 4.8 from macports.

我疯了吗?
