Could this be related to old-vs-new EABI? Is the stack aligned to the same
multiple on entry to main in both old and new executables? The assembler code
looked basically the same, except the stack frame size has changed and a lot
of things that were aligned to an (odd/even) multiple of 8 may now be aligned
to an (even/odd) multiple instead.
