------- Comment #3 from dfranke at gcc dot gnu dot org 2009-01-03 21:39 -------
Not specific to the ALL intrinsic.
$> cat ctor.f90
INTEGER :: i, n, a(5)
n = 5
a = (/ (i, i = 1, n) /)
END
$> gfortran-svn -Warray-temporaries ctor.f90
ctor.f90:3.9:
a = (/ (i, i = 1, n) /)
1
Warning: Creating array temporary at (1)
If N is not a variable, the simplifier takes over and no runtime construction
of arrays is necessary. Not applicable example in #0, of course.
