--- Comment #2 from Ian Lance Taylor <ian at airs dot com> --- Perhaps this would be fixed by adding __attribute__((aligned(4))) to some field of struct Sched in proc.c. This code is all different on trunk/GCC7. I don't know whether it still has the same problem or not. Probably it does but the fix would have to be different.
