8556,Cannot combine synthesized attributes with semantic actions in some cases,Jeff Trull (@…,Joel de Guzman,"The use of ""%="" in rule definitions appears intended to permit simultaneous use of semantic actions and synthesized attributes.  However, in some cases I find I can choose only one.  In particular a rule of this form:

rule<Iterator, std::vector<std::string>()> r;
r = qi::string >> qi::string >> qi::string;

successfully synthesizes its attribute, while the same rule defined this way:

r = (qi::string >> qi::string >> qi::string)[SA]

successfully compiles and runs its semantic action.  However, combining them fails:

r %= (qi::string >> qi::string >> qi::string)[SA]

produces a compile error.  Test case attached.",Bugs,closed,To Be Determined,spirit,Boost 1.52.0,Problem,fixed,,
