11718	No debug output when karma.hpp is included before qi.hpp	anonymous	Joel de Guzman	"In case karma.hpp is included macro karma\nonterminal\debug_handler.hpp::BOOST_SPIRIT_DEBUG_NODE(...) is defined.

In case qi.hpp is included macro qi\nonterminal\debug_handler.hpp::BOOST_SPIRIT_DEBUG_NODE(...) is defined.

both macros are secured by !defined(BOOST_SPIRIT_DEBUG_NODE). Therefore macro is defined only once which is fine.

In case BOOST_SPIRIT_DEBUG is defined expectation is that both macro implementations define equal code. But this is not the case:

- If karma.hpp is included before qi.hpp resulting code is:
  #define BOOST_SPIRIT_DEBUG_NODE(r)  r.name(#r);

- If qi.hpp is included before karma.hpp resulting code is:
  #define BOOST_SPIRIT_DEBUG_NODE(r)  r.name(#r); debug(r)

Therefore debug output is only available when header files are included in the right order. A simple macro extension should solve the issue."	Bugs	new	To Be Determined	spirit	Boost 1.55.0	Problem
