http://www.boost.org/libs/bind/bind.html#err_num_args

tester::Test::do_test takes one argument (the implicit 'this'), you are 
passing two, &x and _1 (the first input argument).

In addition, although this is not relevant for this particular case,

http://www.boost.org/libs/bind/bind.html#err_arg_access

you are trying to access the first argument with _1 but no such argument 
exists since you are calling the result of bind with (), i.e. zero 
arguments.

Summary:

    bind(&tester::Test::do_test, &x)();

or maybe

    bind(&tester::Test::do_test, _1)( x );
