UndefinedBehaviorSanitizer’s unexpected behavior
Or maybe "I learned something"

@bagder about the note on changing "void *" to "struct XXX *" I second your opinion that it would not break the ABI, but I'm also no expert on the C standard. But I believe that change could definitely be made during a major version bump. I'm also interested in the kind of changes that caused uproar.

I think the C standard prohibits that change: https://en.cppreference.com/w/c/language/type#Compatible_types
