sshd signal 11 on -current

A Pi4 running -current reported:

Jan 13 16:23:10 nemesis kernel: pid 53604 (sshd), jid 0, uid 22: exited on signal 11 (no core dump - bad address)

repeatedly. There's no obvious  disruption of operation, existing
ssh connections seem undisturbed. The messages occur in a group of
about fifteen, one second apart. The machine has been up about
three days, with only one occurrence so far. 

Can't tell if this is new or old behavior, I've never manually 
checked /var/log/messages for sshd errors until now and didn't
save the security run email from the 13th.. 

Might it be of significance? 

Thanks for reading,
