        * resolve.c (find_sym_in_expr): New function that returns true
        if a symbol is found in an expression.
        (resolve_allocate_expr): Check whether the STAT variable is
        itself allocated in the same statement.  Use the call above to
        check whether any of the allocated arrays are used in array
        specifications in the same statement.
