9468	Missing include in boost/spirit/home/qi/string/detail/tst.hpp	amdmi3@…	Joel de Guzman	"boost 1.52 on FreeBSD 10.0.

boost/spirit/home/qi/string/tst_map.hpp has a forward declaration of struct tst_pass_through (which is actually declared in boost/spirit/home/qi/string/tst.hpp), however structure's operator() is called in tst_map::find():

{{{
return find(first, last, tst_pass_through());
}}}

This obviously won't compile due to incomplete type. This was discovered on boost 1.52, but since tst_map.hpp haven't changed since then in boost trunk, the bug still exists and needs fixing.

Test program:

{{{
#include <boost/spirit/home/qi/string/tst_map.hpp>

int main() {
	boost::spirit::qi::tst_map<char, int> map;
	int* x;
	map.find(x, x);
	return 0;
}
}}}

clang output:

{{{
