Subject: is.na(valid_date) too often true on SGI MIPS (PR#6814)
Full_Name: George N. White III
Version: 1.9.0
OS: Irix 6.5.21m
Submission from: (NULL) (142.176.61.212)
R-1.9.0 built using the SGI MIPSPro compilers
Installation directory: /usr/local
C compiler: c99 -OPT:IEEE_NaN_inf=ON -mips4 -n32 -O3
-OPT:Olimit_opt=on
C++ compiler: CC -OPT:IEEE_NaN_inf=ON -mips4 -n32 -O3
-OPT:Olimit_opt=on -LANG:std
Fortran compiler: f90 -OPT:IEEE_NaN_inf=ON -mips4 -n32 -O3
-OPT:Olimit_opt=on
Interfaces supported: X11, gnome, tcltk
External libraries: readline, BLAS(generic), LAPACK(generic)
Additional capabilities: PNG, JPEG
Options enabled: shared library, R profiling
Recommended packages: yes
"make check" fails in 2 places due to is.na(..) returning TRUE for valid dates:
> d<-strptime("1910/1/1", "%Y/%m/%d")
> is.na(d)
[1] TRUE
> d
[1] "1910-01-01"
> d<-strptime("1970/1/1", "%Y/%m/%d")
> is.na(d)
[1] FALSE
> d
[1] "1970-01-01"
Incidentally:
> NA+NaN;NaN+NA
[1] NA
[1] NaN
