--- Comment #1 from RazvanN <razvan.nitu1305 at gmail.com> ---
The spec:

"Unions are by default initialized to whatever the Initializer for the first
field is, and if none is supplied, to the default initializer for the first
field's type" [1]

It seems that the resolution to this would be to issue an error (that would
state that the initialization is not used) if we were to stick to the spec.

Or we could modify the spec and allow a single explicit initializer per union.
