From de8606bf73323dfa8395f2dc0a93dc6194ff21b7 Mon Sep 17 00:00:00 2001 From: David Hunt Date: Fri, 16 Jul 2021 14:32:37 +0100 Subject: [PATCH] distributor: fix 128-bit write alignment When the distributor sample app is built as a 32-bit app, the data buffer passed to find_match_vec can be unaligned, causing a segmentation fault due to writing a 128-bit value using _mm_store_si128(). 128-bit align the data being passed in so this does not happen.
