1m is not uapi limit. I'm working on the doc patch to stress that point.
Adding a test to check that it fails at 1m would kinda imply
that it is uapi and I very much want to avoid that.

The purpose of these tests is to stress the verifier to its
internal limits, but not more.
In particular in these two tests 1024, 8, 512, and another 1M
are limits too.
