The dump for 4.5 is from the incorrect code. The behavior of this bug has
change over time, it started for -m64 only with/without print, then it failes
also with -m32, finally at revision 155239 it fails with the print:

...
   print *, temp
   if (any (temp .ne. (/100, 100, 100, 210, 210, 210, 310, 310, 337, 337/))) &
      call abort
end program
[karma] f90/bug% gfc -O3 where_2.f90
[karma] f90/bug% a.out 
         100         100         100         210         210         210       
 310         337         310         310
Abort
[karma] f90/bug% gfc -m64 -O3 where_2.f90
[karma] f90/bug% a.out
         100         100         100         210         210         210       
 310         337         310         337
