Can you try this patch?

Since __attribute__ ((aligned (XX))) doesn't work for stack variables,
is there a gcc option to warn it?

Actually that is not true, it does work in general except when the stack is required only to be not 16byte aligned. I know on powerpc-darwin, it works for sure since there it is required to be 16byte aligned.
