This test fails again after the fix for PR target/48723 [1,2].
PR 48723 fails due to clear omission of accounting, but this PR is more
involved and IMO, the fix there is wrong.
Reopened.

Sure, stack checking is totally broken:

I don't understand how the patch can have been installed. I'd suggest
reverting it ASAP (and assigning PR target/48723 to me).

OK, I have reverted it (I don't have ADA installed, and didn't notice g++
failure...).
