Hi!

I don't think there's something that needs to be fixed. "Undefined"
means "it depends on implementation and we do not want to commit to a
specific behavior here because implementations may change". This is a
fair warning against using implementation details that are not promised
to stay fixed and later crying why next PHP version broke your code.
Because you used undefined behavior. If the behavior is specified as
undefined, that means "don't do this" - so you know it may be broken,
and write better code instead that is not broken.
