The null pointer dereference: https://github.com/mongodb/mongo/blob/dc9e1ee045af74c74360ffce2bec88868b08e1dc/src/mongo/executor/network_interface_tl.cpp#L133-L134
Also consider changing this test to examine the error code on a repair run:
https://github.com/mongodb/mongo/blob/abb1b353648260175c3dfe02ac8ae54c083956f7/jstests/multiVersion/downgrade_to_36_only_with_recovered_data.js#L72-L76
This patch would have surfaced the problem sooner, though I don't think anyone would reasonably pass in --bind_ip with --repair:
