That's a bit weird.  A perhaps plausible explanation would be that the
compiler is unhappy about passing an unsigned argument to a signed
parameter; but if they've tightened it up like that, why no similar
complaint for the 32-bit versions just above these?

Can you try inserting a cast to (volatile int64 *), just to see?
