For quite some time, osmo-pcu has been causing build failures on Debian 8.

You can find a build log e.g. at https://build.opensuse.org/package/live_build_log/network:osmocom:nightly/os...

The visible sign is that for some reasson there are additional log lines present in the output of our unit tests, like:

[ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=FLOW EGPRS) downlink acknowledge [ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=FLOW EGPRS) Final ACK received. [ 127s] +DL packet loss of IMSI= / TLLI=0xffeeddcc: 0% [ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=FLOW EGPRS) changes state from FLOW to WAIT RELEASE [ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=WAIT RELEASE EGPRS) starting timer T3193 [release (DL-TBF)] with 0 sec. 0 microsec, cur_fn=0

where the "+" is the unexpected additional line.

Does anyone have any information about why that is? I don't see any related changes recently.
