Hmm... I don't think it's fixed in R-patched.
I see (in my version of R-patched which is very rarely *not* up-to-date):

[1] "2019-01-30 UTC" NA

If I am right and this is *not* yet ported to R 4.2.2 patched,
I do agree that we should port the patch / fix the problem for
R 4.2.2 patched.

I don't have time for more for the next couple of hours.
