This works, although the following alternative:

template<class T> union function_buffer_
{
    // as before
    mutable T data;
};

size_t const function_buffer_size = sizeof(function_buffer_<char>);

typedef function_buffer_<char[function_buffer_size]> function_buffer;

seems slightly more maintainable as it doesn't perform the size computation 
separately.
