[Bug fortran/16946] New: sum (array, mask) is not accepted

["schnetter at aei dot mpg dot de" <gcc-bugzilla at gcc dot gnu dot org>]

It seems that gfortran does not accept the expression 
 
	sum (array, mask) 
 
The code 
 
program sum_mask 
  implicit none 
  logical :: equal(3) 
  integer :: itype 
  integer :: n 
  itype = sum((/(2**n, n=0, 2)/), equal) 
end program sum_mask 
 
is rejected with the error message 
 
$ ~/gcc/bin/gfortran -c sum_mask.f90  
 In file sum_mask.f90:6 
 
  itype = sum((/(2**n, n=0, 2)/), equal) 
                                1 
Error: Array index at (1) must be of INTEGER type 
 
 
 
According to my draft of Fortran 95, section 13.14.105, this should be legal.  
In my draft of Fortran 2k, section 13.5.12, this should also be legal.
