Research direction
Reproduce rr replay using the reported Debian testing environment and inspect the failure path at Event.cc:75 and Event.cc:340. Trace how event type 31 is recorded and decoded, then verify that replay handles the event without aborting and add or update focused coverage if the relevant test location can be found.
