From 4fe80cf7c3ed3bfb0b818eb6ddf46228178bb3f4 Mon Sep 17 00:00:00 2001 From: "Tobin C. Harding" Date: Mon, 23 Jan 2023 09:46:48 +1100 Subject: [PATCH] Overcome ASAN false positive regression The Memory Sanitizer is giving a false positive at the moment in `nightly`. Adding compiler flags resolves the issue. I didn't grok the exact root cause but this fixes it (cut'n'pasta from the issue [0]).
