From 694f63cad0272ce57e16c7f569ebe1a2f19ccc4b Mon Sep 17 00:00:00 2001 From: Gabriel-Andrew Pollo-Guilbert Date: Mon, 29 Jul 2019 11:14:26 -0400 Subject: [PATCH] Fix: remove uninitialised value Commit 973eac638e4fd introduces an uninitialised value that may prevent shared memory from being allocated. The compiler didn't give any warning because the pointer to the value is sent to a function that don't do anything with it. We simply pass NULL to that function.
