7825	boost::spirit::qi::int_parser<mpz_class> fails to compile on g++ 4.7.2	Andras Kucsma <r0maikx02b@…>	Joel de Guzman	"boost::spirit::qi::int_parser<mpz_class> fails to compile with g++ 4.7.2 in C++11 mode.[[BR]]
It compiles successfully with g++ 4.6.3 and clang revision 170460.[[BR]]
( [http://gmplib.org/ GMP] version is 5.0.5. )

Here's a program which reproduces the problem:
{{{

#include <gmpxx.h>
#include <boost/spirit/include/qi.hpp>

struct MyGrammar : boost::spirit::qi::grammar<const char*> {
public:

	MyGrammar() : MyGrammar::base_type(integerRule) {
		integerRule %= integerParser;
	}

	boost::spirit::qi::rule<const char*> integerRule;
	boost::spirit::qi::int_parser<mpz_class> integerParser;
};

int main() {}

}}}



It compiled with:[[BR]]
g++-4.7 -Wall -Wextra -pedantic bin/main.cpp -o main.o[[BR]]
g++-4.6 -std=c++0x -Wall -Wextra -pedantic bin/main.cpp -o main.o[[BR]]
clang++ -std=c++11 -Wall -Wextra -pedantic bin/main.cpp -o main.o[[BR]]

It failed to compile with:[[BR]]
g++-4.7 -std=c++11 -Wall -Wextra -pedantic bin/main.cpp -o main.o[[BR]]

This is might be a problem in gcc, but I think this information is not sufficient for a gcc bug report.
