The thread on -funsafe-loop-optimizations extinguished without any result. 
Zdenek, maybe you should propose the patch together with adding
-Wunsafe-loop-optimizations to -Wextra, and without adding
-funsafe-loop-optimizations to -O2 for now (maybe it can be revisited for 4.1,
and the 3.3 behavior would be a point in favor of it).
