Re: Bug#698315: [build] openmsx: FTBFS due to invalid alignment assumptions

No idea, C++ is out of my depth.

I know that GCC will need the alignment attribute twice in structs, e.g.

struct foo {
	int bar __attribute__((__aligned__(8)));
	int baz;
} __attribute__((__aligned__(8)));

>idea how this is possible?  Does this happen for other programs as well?

Not normally, although these implicit-alignment-assumptions are very
common, sadly.

(To be honest, I personally think that most code that explicitly checks
for alignment of data types is doing something wrong, and (objectively)
probably something unportable.)

Sure.
