Compiling a kernel with anything but -O for optimization is not supported. gcc
I hit on it by accident (I normally compile with -O). That said, your
claim that gcc with no optimization generates incorrect code is
kind of counter-intuitive, wouldn't you say ?
I think you missed my point, I was just illustrating that optimizer seems
to affect (in my case apparently negate)

I've seen it do weird things with -O0 (mostly with C++). :) It's just
