I'm sorry, but this is completely unreproducible, and the second you say is true you quote as false.
Not sure what you mean -- are you saying "make check" passes on other Irix systems?
d is a list, so can you tell us unclass(d) in both cases?
Sure -- they look OK to me:
d<-strptime("1910/1/1", "%Y/%m/%d")
unclass(d)
$sec [1] 0 $min [1] 0 $hour [1] 0 $mday [1] 1 $mon [1] 0 $year [1] 10 $wday [1] 6 $yday [1] 0 $isdst [1] -1
d<-strptime("1970/1/1", "%Y/%m/%d")
unclass(d)
$sec [1] 0 $min [1] 0 $hour [1] 0 $mday [1] 1 $mon [1] 0 $year [1] 70 $wday [1] 4 $yday [1] 0 $isdst [1] 0
Also, I cannot see those examples anywhere in the R sources so can you please show the actual output you got.
My examples are based on as.POSIXlt from datetime.R. Here are the relevant sections of the output from the tests (if I comment out these sections in reg-tests-1.R and base-Ex.R then "make check" runs fine): $ cd ~/install/R/R-1.9.0/tests gwhite@montigo:/user/gwhite/install/R/R-1.9.0/tests $ gmake reg-tests-1.Rout running code in 'reg-tests-1.R' ...gmake: *** [reg-tests-1.Rout] Error 1 $ tail -20 reg-tests-1.Rout.fail
