Has anybody noticed the way castoroides is randomly failing?

SELECT test_shm_mq_pipelined(16384, (select string_agg(chr(32+(random()*95)::int), '') from generate_series(1,270000)), 200, 3);
! PANIC: stuck spinlock (100cb92f4) detected at atomics.c:30
! server closed the connection unexpectedly
! This probably means the server terminated abnormally
! before or while processing the request.
! connection to server was lost
