Yes, I'm against it, I think that the patch will introduce more issues, and on 
real-life software this time, than it fixes, but you just need to a second 
maintainer to overrule me.

This one is very peculiar though, you need a blatantly out-of-bounds array 
access that is unreachable, so you can avoid it if you avoid generating 
nonsensical code with your code generator.
