From 4a5cc34b46a8bf8d47ec907383be83b6153b9f69 Mon Sep 17 00:00:00 2001 From: Christophe Gisquet Date: Tue, 19 Aug 2014 14:05:56 +0200 Subject: wavpackenc: assert on too small buffer bytestream2_* will not cause buffer overflow, but in that case, this means the allocation would be incorrect and the encoded result invalid. Therefore, assert no overflow occurred.
