Hello all,

I am porting my program from Linux to Windows with boost coroutine2. I found 32bit program throwing boost::context::detail::forced_unwind every time when coroutine destructed. But 64bit program works like charm.

  terminate called after throwing an instance of 'boost::context::detail::forced_unwind'

The program works well on Linux(Ubuntu). Then I tried the official example:

typedef boost::coroutines2::coroutine<int>   coro_t;

coro_t::pull_type source(
    [&](coro_t::push_type& sink){
        int first=1,second=1;
        sink(first);
        sink(second);
        for(int i=0;i<8;++i){
            int third=first+second;
            first=second;
            second=third;
            sink(third);
        }
    });

for(auto i:source)
std::cout << i <<  " ";

Same thing happened.

Platform: windows 7 64 bit
Boost: 1.67/1.69
Compiler: TDM-GCC 5.1 64bit.

Best,
