Yea :(. I tested debug_discard_caches, but not -DRELCACHE_FORCE_RELEASE
-DCATCACHE_FORCE_RELEASE.
Not quite sure what to do about it - it's intentionally trying to test the
case of no invalidations being processed, as that's an annoying edge case with
functions. Perhaps wrapping the function call of the "already dropped"
function in another function that catches the error would do the trick? It'd
be more easily silently broken, but still be better than not having the test.
