[Bug fortran/30549] New: compiler warning in resolve.c: possibly uninitialized use of name

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

The compiler warns that in the function "resolve_function" of resolve.c:, the
variable "name" might be used unintialized. I think gcc is right.

Name is initialized with:
  if (!pure_function (expr, &name) && name)

and later used without extra if(name) in:

  if (expr->value.function.esym && !expr->value.function.esym->attr.recursive)
    {
      gfc_symbol *esym, *proc;
      esym = expr->value.function.esym;
      proc = gfc_current_ns->proc_name;
      if (esym == proc)
      {
        gfc_error ("Function '%s' at %L cannot call itself, as it is not "
                   "RECURSIVE", name, &expr->where);
        t = FAILURE;
      }

      if (esym->attr.entry && esym->ns->entries && proc->ns->entries
          && esym->ns->entries->sym == proc->ns->entries->sym)
      {
        gfc_error ("Call to ENTRY '%s' at %L is recursive, but function "
                   "'%s' is not declared as RECURSIVE",
                   esym->name, &expr->where, esym->ns->entries->sym->name);
        t = FAILURE;
      }
    }
