From 729df81ebc38c84221833adff0fdb6bf609aa2bb 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.
