That’s not the point. Google, for example, are aggressively funding people to throw away perfectly working code and rewrite it in rust, or to at least add rust to projects. librsvg has been such a case for some time already, python-cryptography is, but now we’re losing even freetype (!!!) and, possibly, even the Linux kernel. >https://gcc.gnu.org/wiki/RustFrontEnd That’s assuming it can build the same stuff the same way so it can be used in packaging. >I expect alignment assumptions like that will end up putting more >platforms in the same predicament in future. No, all the other platforms use natural alignment. >"Natural" alignment is meaningless in the context of portable data >structures, as they exist without reference to any particular integer Yeah, but in practice, all we have is ILP32 and LP64; the Windows® world has LLP64 in addition. And natural alignment just means that all the data types’ alignment is their size. (Which kind of makes sense, so you can read them without getting an unalignment trap on SPARC or so.) >Q.

More importantly, and relevant for Qt, struct baa is also 8-byte aligned, and malloc(3) results are usually 8‑ or even 16-byte aligned. bye, //mirabilos -- Gestern Nacht ist mein IRC-Netzwerk explodiert.
