Block header hash calculated not properly

Can’t reproduce block hash calculation:

Here is raw BlockHeader constructed with ethereumjs-block/blockFromRpc:

And hash of this raw data (utils.rlphash(block.header.raw)):

0xf579b522fd8e0f024333c6af3df45061501dd5efa37b553c532cfd5ed89d0035

is not equal to original block hash:

0xc9e562b66933fb390bc935c046eac4223c47f338bc666c4debde94778c2c7534

@davidmurdoch No problem!

https://github.com/trufflesuite/ganache-core/pull/238

I’ll submit another PR to ganache-cli that uses the latest version of ganache-core once this fix is released.

@vpulim thanks!

@davidmurdoch hope for soon release with bug fix 😃
