[Bug c/95052] Excess padding of partially initialized strings/char arrays

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95052 --- Comment #2 from Krzysztof Nowicki --- (In reply to Richard Biener from comment #1) > I'm not sure what you describe as padding is padding. Instead it's valid to > access all elements of the array you declare and thus it must be initialized.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95057 --- Comment #3 from Jakub Jelinek --- It can't. The warning isn't flow sensitive, doesn't know about assignments, conditionals etc. What you are thinking of is something that can be only done much later, but at that point one risks that there is
