--- Comment #17 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
But if I change:
- mutable char data;
+ mutable char data[sizeof (void *) + 2 * sizeof (bool)];
so that the union field occupies the size of some other union members, the
warning is gone, but I still see:
add r5, sp, #292
...
ldm r5, {r0, r1, r2}
...
strb r6, [sp, #293]
