From 1d4ec7b1d6f130818f9b62dea3411d9ee2ff6ff6 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Fri, 20 Jul 2007 12:13:20 -0700 Subject: Fix ZERO_OR_NULL_PTR(ZERO_SIZE_PTR) The comparison with ZERO_SIZE_PTR in ZERO_OR_NULL_PTR() needs to be <= (not just <) so that ZERO_OR_NULL_PTR(ZERO_SIZE_PTR) is 1.
