comp-tests.el just tests the native compiler (in this case the ret type
prediction it does).

I guess here make check does byte-compile comp-tests.el but being the
tests executed with a non-interactive emacs this is never native compiled
afterward (it would hide the issue).

Probably the quickest and easiest fix is just to add the
`no-byte-compile' into comp-tests.el.
