BOOST_DATA_TEST_CASE fails to compile for 4D and higher dimensional grids

[Martin Schulze <spam.martin.schulze@…>]

Compiling the following code with GCC 5.3.0 (C++11/14) I get an error on the second but not on the first test case.

#include <boost/test/included/unit_test.hpp>
#include <boost/test/data/test_case.hpp>

using boost::unit_test::data::xrange;

BOOST_DATA_TEST_CASE(Test_3D_grid,
                     xrange(2) * xrange(2) * xrange(2), a, b, c) {}

BOOST_DATA_TEST_CASE(Test_4D_grid,
                     xrange(2) * xrange(2) * xrange(2) * xrange(2), a, b, c,
                     d) {}

The error reads

/usr/include/boost/test/data/test_case.hpp:107:5: error: no matching function for call to 'bind(<unresolved overloaded function type>, const std::tuple<int, int, int>&, const int&)'
     BOOST_PP_REPEAT_FROM_TO(1, 4, TC_MAKE, _)

Are four and more parameters not supported for data test cases?

The documentation says

BOOST_DATA_TEST_CASE(test_case_name, dataset, var1, ..., varN) { /* datasets of arity N */ }

without giving any limits on N.
