While I fail to see how the "correct value" of cos(4.47460300787e+182)+sin(4.47460300787e+182) can be defined in the 'double' world, cos^2(x)+sin^2(x)=1 and sin(2*x)=2*sin(x)*cos(x) seems to be verified (at least for this value) even if the actual values of sin and cos depends on the optimisation level. Note that sqrt(2.0)*sin(4.47460300787e+182+pi/4) gives a diffeent value for the sum.
