------------------------------+---------------------
 Reporter:  jetdog330@…       |      Owner:  djowel
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  spirit
  Version:  Boost 1.63.0      |   Severity:  Problem
 Keywords:  or sequence       |
------------------------------+---------------------
 This is the simplest I was able to reduce this to.  What is going on here?

 Requirements:
 -Boost 1.62 or 1.63 /w spirit v2
 -C++03/C++11/C++14

 Steps:
 g++ test.cpp && ./a.out

 Expected:
 Success: "x" "a" "b" "c"

 Result:
 Success: "x" "a" "" ""

 {{{
 #include <boost/spirit/include/qi.hpp>

 #include <cstdlib>
 #include <iostream>
 #include <string>

 int main(int argc, char * argv[]) {
     namespace qi = boost::spirit::qi;
     const std::string input("xabc");

     char x = 0;
     char a = 0;
     char b = 0;
     char c = 0;

     const int result = qi::parse(
         input.begin(),
         input.end(),
             qi::char_ >> (qi::lit("Z") | (qi::char_ >> qi::char_ >>
 qi::char_)),
             x, a, b, c
     );

     std::cout << (result ? "Success" : "Failure") << ": "
         << '"' << x << "\" \"" << a << "\" \""  << b << "\" \"" << c <<
 '"' << std::endl;
     return result ? EXIT_SUCCESS : EXIT_FAILURE;
 }
 }}}
