In the past, RepeatNode did not handle empty expressions. It used DCHECK to check if the expression was non-empty. In non-debug mode, this caused _child_block to remain unprocessed, resulting in a deadlock. Now, if the expression is empty, the output block directly outputs _child_block ## Proposed changes Issue Number: close #xxx <!--Describe your changes.--> ## Further comments If this is a relatively large or complex change, kick off the discussion at [[email protected]](mailto:[email protected]) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
