Well, but you said (or at least so I understood) that running the test
for the first time, works.

Then, when you run it multiple times, things start to fail.

That was, in fact, my point... I was making the parallelism between the
fact running only one of those tests works for me and the fact that
running the test for the first time works for you too.

And between the fact that running two tests, one after the other, fails
for me and the fact that running the same tests multiple times fails
for you too.

Yep, agreed. Now I don't think it's related to LTO specifically either.

Although, it's at least a bit of an Heisenbug. I mean, we're seeing it
(with two different setups), but for others, things work fine, I guess?
