It is not a bug. You recursively call A.hello. You want:
p “C #{super}”

Why would you consider this a bug? What on earth were you expecting
it to do? You define a method with no arguments that always calls
itself, and then you call it, and ruby complains from the infinite
recursion.

What else would you have it do?
