boost::spirit::qi::int_parser<mpz_class> fails to compile on g++ 4.7.2

[Andras Kucsma <r0maikx02b@…>]

boost::spirit::qi::int_parser<mpz_class> fails to compile with g++ 4.7.2 in C++11 mode.
It compiles successfully with g++ 4.6.3 and clang revision 170460.
( ​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:
g++-4.7 -Wall -Wextra -pedantic bin/main.cpp -o main.o
g++-4.6 -std=c++0x -Wall -Wextra -pedantic bin/main.cpp -o main.o
clang++ -std=c++11 -Wall -Wextra -pedantic bin/main.cpp -o main.o

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

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

It seems that it was a GMP bug (from the output log) and it has been fixed. Tested on Boost 1.52, GMP 6.1.0 with GCC 4.6.4 and Clang 3.3.
