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

["dfranke at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- 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
