Xuefu Zhang updated PIG-2058:
-----------------------------

    Assignee: Richard Ding  (was: Xuefu Zhang)

The problem introduced by RETURN VOID support. Changing the grammar as follows will solve the problem.

macro_return_clause : RETURNS ( ( alias ( COMMA alias )* ) | VOID )
                   -> ^( RETURN_VAL alias* )
