--- Comment #4 from Benjamin Schulz <schulz.benjamin at googlemail dot com> --- I want to add that i am not using any of the typical things which might cause an optimizer to remove some boundary or something and then enter an endless loop. instead, all the loops here go at maximum from 0 to 8... So i dont have any idea what causes this miscompilation...
