Karma/qi rules in a 0x lambda crashes VC10 with internal compiler error

[Lars Viklund <zao@…>]

Defining a Karma or Qi rule in a C++0x lambda in VC10 RTM crashes the compiler with an internal compiler error.

I have reproduced this with trunk (r61638) and 1.42.0.

Complete test case and build output follows:

#include <boost/spirit/include/karma.hpp>

int main()
{
	[]()
	{
		boost::spirit::karma::rule<char*> r;
	};
}

Well, I'm not sure what we could do about this. It's a compiler bug (as it compiles fine using g++).
