ð Indeed: no bugs – less fun J !
I geeked out a bit and tested this out too on 12.2 ... indeed, seeing the
same behavior. Also interesting that when using ALTER SYSTEM to disable
that event, it doesn't remove it from the other session (as far as
eventdump shows)... so it's telling that even the ALTER command/event
propagation doesn't seem to recognize this event being set (correctly) in
these secondary sessions.
ð Are you also getting an ORA-0600 or ORA-07445 in some dbgd clean-up
function? This would actually confirm a mess-up with the pointers in the
linked list.
Thanks for looking at the problem!

No multitenant, and tested with both new and existing 2. session. Most
probably a bug - quite inconvenient.
However, I’ve managed to reconstruct the doubly linked list, where the
system events are stored:
linked list ptr to root entry:
BCFFDE18+28: *BCFFDE40 = 989423B8
root_Entry:
989423B8+ 0: *989423B8 = 00000080
989423B8+B8: *98942470 = 96DDD200
