$ g++ -O2 -frounding-math bug.cc
$ a.out
123456792 123456792
123456792 123456792
123456792 123456792
123456784 123456784
$ g++ -O2 -fno-inline -frounding-math bug.cc
$ a.out
123456784 123456792
123456784 123456792
123456784 123456792
123456784 123456792

Someone knows if this is the expected behaviour?

GCC bugs apart we definitely need a way to avoid this mess, someone
knows a way?
