13313	Problem when mixing repeat with epsilon parser	Sebastien Matte	Joel de Guzman	"Mixing lazy repeats with epsilon parser (with action) is not working as expected. The attributes are not synthesized as expected. The following example fails:

{{{


std::string s;
size_t c = 0;

BOOST_TEST(test_attr(""aaaaaaaa"", repeat(val(8))[char_ >> eps[ref(c)++]], s) && s == ""aaaaaaaa"" && c == 8);

}}}

It failed because ''s'' is empty (which I don't think it should)

I have made some variation of the same operations (no actions, no lazy operations) and they all works except for this particular case.

See the complete example that I have made from the repeat.cpp test (only the last test fails):

{{{

    {
        using boost::spirit::qi::eps;
        using boost::phoenix::val;
        using boost::phoenix::ref;

        std::string s;
        size_t c = 0;

        s.clear();
        BOOST_TEST(test_attr(""aaaaaaaa"", repeat[char_ >> eps], s) && s == ""aaaaaaaa"");

        s.clear();
        BOOST_TEST(test_attr(""aaaaaaaa"", repeat(8)[char_ >> eps], s) && s == ""aaaaaaaa"");

        s.clear();
        BOOST_TEST(test_attr(""aaaaaaaa"", repeat(val(8))[char_ >> eps], s) && s == ""aaaaaaaa"");

        s.clear();
        c = 0;
        BOOST_TEST(test_attr(""aaaaaaaa"", repeat[char_ >> eps[ref(c)++]], s) && s == ""aaaaaaaa"" && c == 8);

        s.clear();
        c = 0;
        BOOST_TEST(test_attr(""aaaaaaaa"", repeat(8)[char_ >> eps[ref(c)++]], s) && s == ""aaaaaaaa"" && c == 8);

        s.clear();
        c = 0;
        BOOST_TEST(test_attr(""aaaaaaaa"", repeat(val(8))[char_ >> eps[ref(c)++]], s) && s == ""aaaaaaaa"" && c == 8);
    }
}}}
