ash: [VAR] Fix poplocalvar on abnormal exit from function
Upstream commit: Date: Thu, 27 May 2010 11:32:55 +0800 [VAR] Fix poplocalvar on abnormal exit from function The new localvar code broke the abnormal exit from functions and built-ins by not restoring the original localvar state. This patch fixes this by storing the previous localvar state so that we always unwind correctly in case of an abnormal exit.
