I have played a bit around with the following (which has to be compiled on a
system with 32bit size_t):

   real(8), dimension(1024*1024*1024) :: m
   m(1)= 0
   print *, 1024*1024*1024 ! * 8 -> overflow
   print *, huge(3)
   print *, 2_8**32
   print *, 4_8*1024*1024*1024
   end

However, I fail to get any compile- or run-time error. Expected: As with the
following code, one gets a compile-time error:

$ gfortran -m32 hjff3.f90
.test.f90:1:0: error: size of variable ‘m’ is too large

   real(8), dimension(huge(3)) :: m
   m(1)= 0
   end
