From 561639a68c6a5468eaa95912592f9d01ba9dcbdd Mon Sep 17 00:00:00 2001 From: Denys Vlasenko Date: Fri, 7 Oct 2016 04:28:33 +0200 Subject: [PATCH] ash: all blocks in function node copying must be SHELL_ALIGNed Previous commit probably introduced a bug: non-matching size calculation in size counting and actual copying caused by SHELL_ALIGN being applied differently! This won't bite if string sizes are also SHELL_ALIGNed. Thus fixing.
