Thanks artafinde for the clarification, and thanks also Polarian, your explanations were
worth reading!

This is indeed what I'm talking about, sorry I should've read the comments on Aurweb
before posting here. Since the problem has already been reported, I feel like there's no more to do but waiting if the maintainer is willing to backport the patch.

I totally understand that packages may break, I was kind of wondering why upstream would have released a non-compiling version, but I have the explanation now.

Have a good day/night,
