That's the same problem. We have no control over whether the system has
enough resources that we hit an arbitrary recursion limit before
there's a crash.
See many, many discussions over the years, including one quite recently,
and another not so many months ago.
Calling _normal recursively is in some cases sensible, in particular
if you've pruned the command line since the first call
(c.f. _precommand), so trying to check for a real problem isn't that easy.
