8695	boost::polygon faillure with optimizations enabled on g++-4.7.2	hodevel@…	Andrii Sydorchuk	"Following program does not return same results depending on optimization level.
When using -00 with g++-4.7.2, area is 100 (good result).
When using -02, area is 0 (bad result).

Other compilation options:
-Wall -std=c++0x -g
