The stack pointer (%sp) must always be doubleword-aligned. When you are
doing things like sub %sp,4,%sp, you are breaking this rule. Although I
don't know the exact problem that you are facing, this could be one of
them. I would also wonder about why you are enlarging the frame using a
"sub" instruction when the "save" instruction does this work for you ?
Hope this helps.
