Strange. That smells like a compiler bug to me.

But I can't read powerpc assembly code - it's been too many years, and
even back when I did read it I hated how the register "names" worked.

Maybe it was never the args array, and it was about the other fields.
Not that that makes any sense either, but it makes more sense than the
compiler turning a series of volatile accesses into a memset.
