13443	boost.test data driven test fails to compile when number of samples greater than 9	g.sermaidis@…	Raffi Enficiaud	"Hello, 
It looks like boost.test fails to compile a simple data driven test with 10 samples. I am using clang++ (Apple LLVM version 9.0.0 (clang-900.0.39.2))with C++14 flags enabled. According to this help page <http://www.boost.org/doc/libs/1_66_0/libs/test/doc/html/boost_test/utf_reference/test_org_reference/test_org_boost_test_dataset.html> 
the compiler should have no problem dealing with number of samples greater than BOOST_TEST_DATASET_MAX_ARITY which is 10 by default. Even defining BOOST_TEST_DATASET_MAX_ARITY to 20 prior to including any headers still fails to compile with the following error: 
/usr/local/include/boost/test/data/test_case.hpp:182: error: no matching function for call to 'bind' 
                           boost::bind( &TestCase::template test_method<Arg...>, 
                           ^~~~~~~~~~~ 

Here is the relevant code:
