BOOST_ASIO_REBIND_ALLOC question

Hi,

I‘m trying boost aiso examples on my andoird mobile phone.

Unfortunately!

When I compiled the time_t_timer example, using c4doird app by g++ -std=c++17 on android, the g++ complained:

no member allocate and deallocate

at the line 190 in handler_alloc_helpers.hpp, and I found it occurred when compiling the parameter of async_wait:

    timer.async_wait(
        [](const boost::system::error_code& /*error*/)
        {
          std::cout << "timeout\n";
        });

After I

1. updated the line 59 in memory.hpp to:

   typename std::allocator_traits<alloc>::template rebind_alloc<t>::other

or,

2. added #define BOOST_ASIO_DISABLE_CXX11_ALLOCATORS before #include <boost/asio.hpp>,

The problem disappeared!

Is there a problem here?

This issue was moved by chriskohlhoff from boostorg/asio#275.

At first glance, it seems that there is a bug and your first solution should be applied.
