Only partly. The example in the initial code is fixed. However, if you change
it to aligned(8) instead of aligned(16), it no longer aligns. See comment 17.
Using PREFERRED_STACK_BOUNDARY_DEFAULT instead of STACK_REALIGN_DEFAULT would
have fixed this, but maybe this is supposed to be considered a bug with
-mstackrealign. I don't know. I've asked multiple times what the difference
between the two is actually supposed to be, without answer.
