We don't have an Irix system on which they fail _AND_ your examples
are not in the R sources. N.B. as.Date and is.na(strptime()) are not the
same code, and your second example is still not explained.
However, you reported to R bugs, not to Irix bugs, and no other R system
has shown this behaviour. So the finger is pointing elsewhere.
