--- Comment #5 from Mikael Morin <mikael at gcc dot gnu.org> 2013-04-13 10:32:46 UTC --- (In reply to comment #0) > tmp(2) = r(1) + 0.25 ! r(1:4) == 0 > tmp(2) = r(2) + 0.25 > tmp(3) = r(3) + 0.25 > tmp(2) = r(4) + 0.25 > r(2) = tmp(2) ! = 0.25 > r(2) = tmp(2) ! = 0.25 > r(3) = tmp(3) ! = 0.25 > r(2) = tmp(2) ! = 0.25 > -> sum(r) = 0.5 > By the way, it's rather: tmp(1) = r(2) + 0.25 ! r(1:4) == 0 tmp(2) = r(2) + 0.25 tmp(3) = r(3) + 0.25 tmp(4) = r(2) + 0.25 r(2) = tmp(1) ! = 0.25 r(2) = tmp(2) ! = 0.25 r(3) = tmp(3) ! = 0.25 r(2) = tmp(4) ! = 0.25 -> sum(r) = 0.5
