[R] R-3.4.0 fails test

[Patrick Connolly]

After installing R-3.4.0 I ran 'make check'  which halted here:

$ > tail reg-tests-1d.Rout.fail -n 16
> ## format()ing invalid hand-constructed  POSIXlt  objects
> d <- as.POSIXlt("2016-12-06"); d$zone <- 1
> tools::assertError(format(d))
> d$zone <- NULL
> stopifnot(identical(format(d),"2016-12-06"))
> d$zone <- "CET" # = previous, but 'zone' now is last
> tools::assertError(format(d))
> dlt <- structure(
+     list(sec = 52, min = 59L, hour = 18L, mday = 6L, mon = 11L, year = 116L,
+          wday = 2L, yday = 340L, isdst = 0L, zone = "CET", gmtoff = 3600L),
+     class = c("POSIXlt", "POSIXt"), tzone = c("", "CET", "CEST"))
> dlt$sec <- 10000 + 1:10 # almost three hours & uses re-cycling ..
> fd <- format(dlt)
> stopifnot(length(fd) == 10, identical(fd, format(dct <- as.POSIXct(dlt))))
Error: identical(fd, format(dct <- as.POSIXct(dlt))) is not TRUE
Execution halted

... so, of course, the remaining tests aren't done.

AFAICT, that test will fail anywhere outside of tzone CET, but I could
be missing something.

What is the point of this test and is there a better way to move on to
the remaining tests besides editing the corresponding .R file?

Changing the line

> stopifnot(length(fd) == 10, identical(fd, format(dct <- as.POSIXct(dlt))))
to
> stopifnot(length(fd) == 10, identical(fd, format(dct <- as.POSIXlt(dlt))))
                                                                ^^^^
would pass.  But would that be any use?
