From f391fdd8e0fbaf3749819cfa0cd9b478f3630a7d Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Thu, 13 Feb 2020 13:27:18 +0100 Subject: scanner: use list_is_first() from scanner_pop_indesc() !list_empty() always stands true since the list is never empty when calling scanner_pop_indesc(). Check for list_is_first() which actually tells us this is the initial input file, hence, state->indesc is set to NULL.
