From 9c62fc69a8eb9f72da054f908704acbb14a6caa6 Mon Sep 17 00:00:00 2001 From: Stefan Sperling Date: Fri, 16 Mar 2018 10:23:34 +0100 Subject: fix bug in parse_cell_id_ci_list() Cell ID lists with CI were misparsed because parse_cell_id_ci_list() failed to report the amount of consumed bytes to its caller. Also add a regression test which uncovered the bug.
