[Bug fortran/31919] New: ICE in fold_binary in fold-const.c

[keinstein_junior at gmx dot net]

On amd64 debian gfortran fails (both trunk and recent 4.2 from GFortran wiki):

module materials
   implicit none
   integer,parameter :: dr = kind(1.0d0)
   private
   type md_field
       real(dr),dimension(1:3,1:99) :: realspeed
       real(dr),dimension(1:99) :: mass,kinenergy
   end type md_field
contains


   function getTemperature(x,selector) result(temp)
      type(md_field),intent(in) :: x;
      integer,dimension(:),intent(in),optional :: selector;
      real(kind=dr) :: temp;

! realspeed has wrong dimensions
      print *,min(x % kinenergy,x % realspeed)

   end function getTemperature
end module materials


Output is:
$ gfortran-trunk matbug.F90
matbug.F90: In function ‘gettemperature’:
matbug.F90:12: internal compiler error: in fold_binary, at fold-const.c:8923
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

It's not valid I guess, but gfortran should not fail.

[Bug fortran/31919] ICE in fold_binary in fold-const.c

------- Comment #1 from dfranke at gcc dot gnu dot org  2007-05-14 16:39 -------
The problem is the handling of arrays in the MIN intrinsic. The reporter
probably wanted "MIN(MINVAL(x%kinenergy), MINVAL(x%realspeed))" as the
dimensions of REALSPEED and KINENERGY are not conformable.

$> sunf95 pr31919.f90
"pr31919.f90", Line = 10, Column = 35: ERROR: All of the actual arguments to
this intrinsic call are not conformable to each other.

Slightly reduced testcase:

$> cat pr31919.f90
module materials
   type md_field
       real,dimension(10, 10) :: realspeed
       real,dimension(10) :: mass,kinenergy
   end type md_field
contains
   real function getTemperature(x)
      type(md_field),intent(in) :: x;
      print *, min(x%kinenergy, x%realspeed)
   end function getTemperature
end module materials

Minimal testcase:

INTEGER :: a(2), b(2,2)
PRINT *, MIN(a, b)

[Bug fortran/31919] [4.1/4.2 only] min/max do not check array conformance

[dfranke at gcc dot gnu dot org]

------- Comment #6 from dfranke at gcc dot gnu dot org  2007-06-16 22:53 -------
Not a regression, no backport to 4.2. Closing.
