It baffles me too. Yet it still fails like clockwork here.

Well, "crossing filesystems" and "large enough" are admittedly a
working hypothesis. I don't really know that's what makes it fail. I
just know that I could create other cases which do not fail, out of
these conditions.

I take this means you still cannot reproduce... I'm sorry, I don't
know what else I can try, I'm out of my depth here. Do you have
anything you'd like me to try? Can anyone else reproduce this, or is
it really just me?

The encrypted partition is open and mounted, as far as the system can
see, it is just another ext4 partition. More clearly, it cannot be
encryption per se, since the "/tmp/" folder is not encrypted at all,
it is just a tmpfs mount. It's fstab entry is:

    tmpfs /tmp tmpfs nodev,nosuid,size=6G 0 0

Of course, it might still be "or something". But I don't do anything
out of the ordinary here that I'm aware of.
