OsmoMSC crashes on LUR
The problem may be reproduced using OsmocomBB and a virtual SIM-card
(mobile configuration attached). Register a subscriber in HLR and try
to perform LUR.
LAPDm + A-bis PCAP trace is attached.
Valgrind trace of the binary is also attached.

Looking at the trace, it's the most normal Location Updating Request there is, and that works for me (TM):
I have tossed up a quick msc_vlr_test to send/receive exactly the messages found in your trace. Running the resulting test doesn't crash and valgrind does not show any "Invalid read of size 4". See https://git.osmocom.org/osmo-msc/commit/?h=neels/os2983&id=dbaf3bd3fed4d433cb7851f9eaea8b3e8db5e59e
Would there be anything special about using OsmocomBB? Are you sure you can reproduce the issue with everything uninstalled / compiled from scratch? (has happened to me more than once)
