From b34499f5c851d1a70db95b56bd02eff0329d4a1a Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Fri, 23 Aug 2013 21:58:55 +1000 Subject: [BUILTIN] Fixed argument parsing crash in test When nexpr gets an unexpected EOI, this may cause crashes further up the call chain because we've advanced t_wp too far. Fix it by checking for EOI in nexpr and only advancing t_wp if we've got more arguments.
