Is 'b' an addressable variable or is it a regular local stack variable?
If the latter, then this is a buglet in the conversion to GIMPLE form.
We should probably check whether the array index is already a gimple
register before creating b.0.

It's not a big issue, though.  Copy propagation should get rid of that
very early on, but I agree that it would be worth fixing.
