I despise the "may be used uninitialized" warning. It either is or it isn't.

In this case, yes it looks like it is. So it should say "is used uninitialized".
(They were 2 separate warnings in gcc for years and it was a fountain of false
positives to the point I learned the "int a=a;" initializers from the kernel to
SHUT IT UP.

Anyway, appled.
