[Boost-users] [bind] Binding a bound function does not compile

Hello,

The following code does not compile (gcc 4.3.2, boost 1.40).

#include <boost/bind.hpp>
using boost::bind;

void foo(int) {}

template <class F>
void invoker(F f) { f(); }

template <class F>
void call(F f)
{
    bind(invoker<F>, f)();
}

int main(int argc, char* argv[])
{
    call(bind(foo, 1));

    return 0;
}

I am passing a bound function as an argument to bind. The binding itself seems to work but the call fails. In other words, if I change the line in call() to

bind(invoker<F>, f);

it compiles just fine.

Any ideas?

Thanks,
Eugene
