Both testcases, the original report as well as comment #2 still produce
temporaries with gcc version 4.6.0 20100509 (experimental) (GCC).

Another test case:

$ cat foo.f90
program main
  real, dimension(2,2) :: a
  real, dimension(2) :: b
  call random_number(a)
  b = sum(a,dim=1) + 0.4
end program main
$ gfortran -Warray-temporaries foo.f90
foo.f90:5.6:

  b = sum(a,dim=1) + 0.4
 1
Warning: Creating array temporary at (1)
