It is what I don't know. controlfile only says  "incorrect checksum in control 
file". It seems to me that CRC computing does not work correctly. I check 
pg_control footprint and it is same for 32/64. It seems to me a false positive

Footprint switch should help show you why it is incompatible and also protect 
you during development to break some structure.
