the fortran compiler crashes when trying to compile the following test program
: 

      subroutine probleme(p)


      real(kind=8), dimension(:) :: p

      integer :: nx = size(p, 1)
      integer :: nix

      nix = nx

      end subroutine




The error reported by the compiler is :

test.f: In function ‘probleme’:
test.f:2: erreur interne du compilateur: dans gfc_conv_constant, à
fortran/trans-const.c:348
Veuillez soumettre un rapport complet d'anomalies,
avec le source pré-traité si nécessaire.

The compilation command was : gfortran test.f


The gfortran -v is :

[fxcoudert at gcc dot gnu dot org]

------- Comment #6 from fxcoudert at gcc dot gnu dot org  2007-03-20 23:51 -------
I think test.f is not valid Fortran, because size(p,1) is not a valid
specification expression. See 7.1.6 of the F2003 standard: it is a array
inquiry function (size) with an argument that is a variable (p) whose
properties inquired about *are dependent* on the upper bound of the last
dimension of an assumed-size array. So, it's invalid.

Now, we actually accept it because SIZE is a specification inquiry, and we
don't check things any further. This part (check_inquiry and its callers in
expr.c) need some rewriting to go along with the standard.
