From e9a2e665b25efc3fd2c8d800c85cf74eab7997dc Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Stefan=20Br=C3=BCns?= Date: Sat, 29 Jun 2019 20:28:24 +0200 Subject: [PATCH] Explicitly default operator= for Vec MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Due to the explicitly declared copy constructor Vec::Vec(Vec &) GCC 9 warns if there is no assignment operator, as having one typically requires the other (rule-of-three, constructor/desctructor/assginment). As the values are just a plain array the default assignment operator does the right thing. Tell the compiler explicitly to default it.
