Description

While testing osmux related stuff (WIP), osmo-mgw sometimes sends a 400 FAIL message (because it's WIP, I know why but it's no related to this issue).
When that happens, osmo-bsc ends up in a heap-use-after-free catched by ASan.
That happens after last patches merged in osmo-mgw/osmo-bsc related to osmo-msc handover afaik.
