I'm surprised. I guess some later patch accidentally fixed it.
For the record I have tested on x86/64, so we may see a few more breakage
things, but I hope that the number will be quite small in comparison to the

I expect we'll see a bunch more gramlins like this. And I assume
this
fixes:

LGTM, thanks!
