I agree that the above is wrong, i.e., a bug in current  R-devel.

I have no intention of hijacking this thread, but I wonder whether this
is a good opportunity to mention that the 32 bit build of R-devel falls
over on my machine since 25 September.  It fails one of the regression
tests in reg-tests-1d.R.  The final lines of reg-tests-1d.Rout.fail
are:

tools::Rd2txt(rd, out <- textConnection(NULL, "w"), fragment = TRUE)
stopifnot(any(as.character(rd) != "\n"),

+           identical(textConnectionValue(out)[2L], "LaTeX"));
close(out)

## empty output in R <= 4.2.x


## as.POSIXlt(<very large Date>)  gave integer overflow
stopifnot(as.POSIXlt(.Date(2^31 + 10))$year == 5879680L)

Error: as.POSIXlt(.Date(2^31 + 10))$year == 5879680L is not TRUE
Execution halted


I should have reported this earlier, but somehow did not find the time
to do so.  So I thought I mention it here. :)

Cheers,
