| ! PR20866 - A statement function cannot be recursive. |
| ! Contributed by Joost VandeVondele <jv244@cam.ac.uk> |
| ! |
| ! Modified 20051110 to check that regressions PR24655 and PR24755 |
| ! are fixed. Thanks to pavarini@pv.infn.it and tdeutsch@cea.fr for |
| ! the tests. |

| ! Test check for recursion via other statement functions, string |

| ! references. |
