My colleagues and I often lament how gcc is just so much smarter than all of us. Usually after spending a day figuring out why our code wasn't working, only to discover that gcc was doing something "clever".

This one sounds almost like peephole optimization of sorts. How exactly is that "clever"?

I assumed it was the ironic sense—it was intended to be clever but just ended up being a bug.
