From ccd6ebbc9ab4026a77ac2844e15ea35adfe788be Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Mon, 14 Aug 2017 10:36:55 +0200 Subject: don't ask an uninit _system for supported archs A libapt user who hasn't initialized _system likely has a reason, so we shouldn't greet back with a segfault usually deep down in the callstack for no reason. If the user had intended to pick up information from the system, _system wouldn't be uninitialized after all.
