Spirit X3 没有匹配函数调用 'move_to'

Question

为什么编译不通过？（注释 r3 会编译，但我想要规则中的分号）

#include <boost/spirit/home/x3.hpp>
#include <boost/fusion/include/adapt_struct.hpp>

#include <string>
#include <vector>

struct v
{
    std::string value;
};

BOOST_FUSION_ADAPT_STRUCT
(
    v,
    (std::string, value)
)

using namespace boost::spirit::x3;

auto r1 = rule<struct s1, std::string>{} = lexeme[+alpha];

auto r2 = rule<struct s2, v>{} = r1;

using ast = std::vector<v>;

auto r3 = rule<struct s3, ast>{} = *(r2 >> ';');
//auto r3 = rule<struct s3, ast>{} = *r2;

int main()
{
    std::string script("a;");
    auto begin = script.begin();
    auto   end = script.end();

    ast a;

    phrase_parse(begin, end, r3, space, a);

    return a.size();
}

正如@jv_ 所建议的，我已经下载了 develop 分支。之后代码无需任何更改即可运行。
