I'm betting that this is a memory-clobber problem in that custom datatype.
The reason the symptoms come and go when varying unrelated stuff is that
it might be chancing to clobber momentarily-unused memory rather than
live data structures. (In the above example, the queue of pending FK
trigger events is likely what got clobbered.)
