Hi, compiled with -Wall -Wextra the wollowing lines don't complain about a

  return a;

Yes, you're missing -Winit-self

Thanks.

Confusing... extra option for that?

The message with -Wuninitialized -Winit-self is
warning: 'a' is used uninitialized in this function [-Wuninitialized]

Is there a special reason why this is not part of Wall or Wextra?
