Yeah, that commit looks very innocuous. I'm surprised it would even
change any code generation, but it's very possible that it ends up
affecting some code layout or something almost by mistake.

I'd be inclined to think that the problem is very timing-sensitive,
and has probably been there for a while, and some random moon phase
just made it happen now.
