Cancun failures

[holiman]

I'm tryng to get the most recent tests to work with geth, and have a PR opened there:ethereum/go-ethereum#28337

Currently investigating the very first test in /cancun/eip5656_mcopy/mcopy_memory_expansion/mcopy_huge_memory_expansion.json, called 000-fork=Cancun-from_existent_memory-successful=False--max_dest_single_byte_expansion.

[user@work go-ethereum]$ go run   ./cmd/evm/ --json  blocktest ./tests/spec-tests/fixtures/cancun/eip5656_mcopy/mcopy_memory_expansion/mcopy_huge_memory_expansion.json

This is the (complete) state that I get EDIT: not accurate

        }
    }
}

Curious to know what the expected state is...?

Hi @holiman, please see ethereum/go-ethereum#28337 (review).

Regarding the problem in this ticket, I just built https://github.com/ethereum/go-ethereum/tree/509a64ffb9405942396276ae111d06f9bded9221 and used the fixtures_develop.tar.gz from release v1.0.5. Running the following works locally for me:

/home/dtopz/code/github/ethereum/go-ethereum/build/bin/evm --version
# -> evm version 1.13.4-unstable-509a64ff-20231013
/home/dtopz/code/github/ethereum/go-ethereum/build/bin/evm blocktest ./fixtures_dev/cancun/eip5656_mcopy/mcopy_memory_expansion/mcopy_huge_memory_expansion.json

Which geth branch are you using? Respectively which version of the fixtures are you using?

Thanks for the help, it's sorted now!
