Right, ok. That's not extremely urgent then as I think the simple one
also works with my collection of classic mono samples. It does not
work on PPC architectures, but that was more of a "recreational
tinkering" thing than something I insist we should have :-).

Yes, that one should be fine, I imagine :-)

Ok, that makes me happy. That means I did not muck up merging
(go-flux) -though that one needs a cleanup, I can do better now. and
it also means I can still write a nice loop :-)

I think so. We might theorise there is some variable in the ringbuffer
that is implicitly 32 or 64 bits, gets set to 64 on your side and to
32 here. That would explain it.

No, no clear errors, those I would have investigated. I might be
getting compile-time warnings though, I could look into that more
closely. I noticed while looking into those earlier errors that I
could change a lot of that stuff without GCC complaining, that was a
bit disturbing to me as some of what I tried was quite plainly
"wrong".

At least this narrows it down significantly; I suspect something
int-size related in one of your last few commits. Hope testing
Redacted was a fun experience, I could imagine it was a slightly
disorienting experience as that example accidentally involved quite a
lot of my stuff. Must be not unlike a stranger re-decorating your
livingroom :-)

Cheers,
