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
