We should give a message such as ifort:
  The initialization shall not appear for this object name.   [F]
  This array or function or substring is invalid in constant expressions.
[IRAND]
The place to change is check_init_expr; maybe gfc_intrinsic_func_interface.
Giving an error should fix both problems.
