The changes to consensus/tx_verify.cpp need to be backported. It's not in our codebase.

This revision now requires changes to proceed.Jul 5 2019, 21:25

The first change to consensus/tx_verify.cpp to GetP2SHSigOpCount() is already there. Its been turned into the function .GetOutputFor():

  const CTxOut &CCoinsViewCache::GetOutputFor(const CTxIn &input) const {
	    const Coin &coin = AccessCoin(input.prevout);
	    assert(!coin.IsSpent());
	    return coin.GetTxOut();
  }

The second change is to GetTransactionSigOpCost() but that should have been added in D1739. See https://github.com/bitcoin/bitcoin/pull/8329/files for comparison.
