Sorry, I misread that part. I think your patch makes sense - but for 
some reason it does not seem to be required.

For my example, the value is set via: resolve_fl_variable -> 
resolve_fl_variable_derived, which contains:

  /* Assign default initializer.  */
  if (!(sym->value || sym->attr.pointer || sym->attr.allocatable)
&& (!no_init_flag || sym->attr.intent == INTENT_OUT))
    {
      sym->value = gfc_default_initializer (&sym->ts);
    }

Thus, I really wonder whether the resolve_symbol's version is used at all.

OK - though one could think of plugging into the resolve_fl_variable or 
resolve_fl_variable_derived code.
