[Bug fortran/31218] ICE on valid code with gfortran

[jvdelisle at gcc dot gnu dot org]

------- Comment #4 from jvdelisle at gcc dot gnu dot org  2007-05-04 02:47 -------
The ice is happening here:

/* Create an array constructor from an initialization expression.
   We assume the frontend already did any expansions and conversions.  */

tree
gfc_conv_array_initializer (tree type, gfc_expr * expr)
{
  gfc_constructor *c;
  tree tmp;
  mpz_t maxval;
  gfc_se se;
  HOST_WIDE_INT hi;
  unsigned HOST_WIDE_INT lo;
  tree index, range;
  VEC(constructor_elt,gc) *v = NULL;
gfc_show_expr (expr);
  switch (expr->expr_type)
    {
    case EXPR_CONSTANT:
    case EXPR_STRUCTURE:

The comment indicates that the initialization expression should already be
expanded.  For the test case given, expr->expr_type is FUNCTION for which there
is no case.  The function needs to be evaluated before getting here.
