| ! First the original problem: vocab_swap not being referenced caused |
| ! an ICE because default initialization is used, which results in a |
| ! call to gfc_conv_variable, which calls gfc_get_symbol_decl. |

| ENDSUBROUTINE extend_lists1 |
| |
| ! Curing this then uncovered two more problems: If vocab_swap were |
| ! actually referenced, an ICE occurred in the gimplifier because |
| ! the declaration for this automatic array is presented as a |
| ! pointer to the array, rather than the array. Curing this allows |
| ! the code to compile but it bombed out at run time because the |
| ! malloc/free occurred in the wrong order with respect to the |
| ! nullify/deallocate of the allocatable components. |
