[Boost-users] Signal with return value will crash

Hi,

I tried the signals, the code below will crash

#include <boost/signal.hpp>
int _tmain(int argc, _TCHAR* argv[])
{
        boost::signal<int(int)> _sig;
        _sig(10);

        return 0;
}

but code below works well

#include <boost/signal.hpp>
int _tmain(int argc, _TCHAR* argv[])
{
        boost::signal<void(int)> _sig;
        _sig(10);

        return 0;
}

The only difference is one has return value, the other doesn't, is this a bug or by design?

Thanks,
Wang Yun
