Node crash right after dev started miner

This happens during the mainnet launch.

Reproduce

At block 0, node start smoothly.

At block about 3, node crashed. During the mainnet launch, dev started to run miner, and a fresh node just crashed. After empty db, tried to start the node again, same error message will appear. More than one miners posted the same error message. This could be an issue.

Rejoin the chain at around block 20.

It seems to be some edge cases.
