dromedary's issue seems to be alignment:
TRAP: UnalignedPointer("(((uintptr_t) ((uintptr_t)(ptr)) + ((8) - 1)) & ~((uintptr_t) ((8) - 1))) != (uintptr_t)(ptr)",
File:"../../../../src/include/port/atomics.h", Line: 452)
2017-08-16 11:11:38.558 EDT [75693:3] LOG: server process (PID 76277) was terminated by signal 6: Abort trap

Not sure if this is your bug or if it's exposing a pre-existing
deficiency in the atomics code, viz, failure to ensure that
pg_atomic_uint64 is actually a 64-bit-aligned type. Andres?
