[Bug fortran/19904] New: Division by zero leads to error

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

I want to define a parameter that contains a nan.  When I use a division by 
zero in a parameter statement, gfortran aborts with an error instead of 
setting the parameter to nan.  (The Intel Fortran compiler accepts this 
parameter statement without warning.) 
 
subroutine x 
  implicit none 
  double precision, parameter :: zero=0, nan=0/zero 
end subroutine x 
 
$ ~/gcc/bin/gfortran -c zero.f90 
 In file zero.f90:3 
 
  double precision, parameter :: zero=0, nan=0/zero 
                                             1 
Error: Division by zero at (1) 
 
$ ~/gcc/bin/gfortran --version 
GNU Fortran 95 (GCC 4.0.0 20050126 (experimental))
