        * trans-expr.c (gfc_conv_procedure_call): Allocatable scalar
        function results must be freed and nullified after use. Create
        a temporary to hold the result to prevent duplicate calls.
        * trans-stmt.c (gfc_trans_allocate): Rename temporary variable
        as 'source'. Deallocate allocatable components of non-variable
        'source's.
