From 2af8df02cca7fd4b584575eac304cd03fa23f5cc Mon Sep 17 00:00:00 2001
From: Darren Kenny <darren.kenny@oracle.com>
Date: Thu, 22 Oct 2020 13:54:06 +0000
Subject: [PATCH] gnulib/regcomp: Fix uninitialized token structure
The code is assuming that the value of br_token.constraint was
initialized to zero when it wasn't.
While some compilers will ensure that, not all do, so it is better to
fix this explicitly than leave it to chance.
Fixes: CID 73749
