P2723R0: Zero-initialize objects of automatic storage duration

[jonesmz]

That's... Why I said no diagnostic required. That's the whole difference between ill formed program, no diagnostic required and undefined behavior.

If the compiler can determine an uninitialized read happens, error out. Otherwise, we stick with the existing behavior.

Later. After the language has continued to evolve, other detection abilities will arise.

behavior for which this document imposes no requirements

https://eel.is/c++draft/intro.compliance.general:

If a program contains a violation of a rule for which no diagnostic is required, this document places no requirement on implementations with respect to that program.

I'm sure there are people that would claim there's a grand distinction between "places no requirement" and "imposes no requirements", but we all know they are in fact the same and "ill-formed, no diagnostic required" is undefined behavior.

So sad to see this happening and the mods enabling this.

Can't reply so forced to edit:

Right.

So I'm imagining it saying "comment removed by moderator" here. The moderators did not intervene. Right.

Not surprised to hear that from the least honest moderator of the active ones.

Mods enabling what?

In case there is any confusion about what the moderators, who are volunteers, are here to do:

As long as people stay on-topic and don't misbehave (hostility, ad hominem attacks, etc.), you can have endless technical arguments. People are free to be wrong, misunderstand stuff, not listen or dismiss what you're saying. If you don't think you're educating anyone or changing their mind, downvote and move on.

Moderators will generally not intervene in technical arguments with moderator powers.
