I am guessing it would not fix it. I can reproduce the problem if I add __attribute__((aligned(16))) to the "stack" variable. That is sufficient for GCC to emit an offending movaps instruction for me. The -ftrivial-auto-var-init= option will not affect that initialization. > But anyway all of these pretty much sound reasonable. We don't need much > to happen in the stub here, simpler is better. Yeah, and I guess c) really is sufficient by itself. Benjamin
