Yes, they work now.

I mentioned them partly because the commit description said overflow for large n and partly to be considered for regression tests.

Thank you.

"But" all these work now (in R-devel, rev >= 73094) as they should,
at least for me, right?

Are you mentioning the  "small n" examples so we could use them
as regression tests  (instead of the regression test I had added
to tests/reg-large.R  which needs enough GB and is slowish ) --
or are you seeing a platform where the above cases still don't
work in (new enough) R-devel ?
