• what you expected to happen

I compiled the following contract with solc v0.4.9 and deployed it to Eris DB. I expected it to work without errors as it did when compiled by solc v0.3.4.

    contract SimpleStorage {
        uint storedData;

        function set(uint x) {
            storedData = x;
        }

        function get() constant returns (uint retVal) {
            return storedData;
        }
    }

@NodeGuy do you mean the actual "Invalid" Opcode and we don't account for it?

[NodeGuy]

Sorry, I hit Save by accident before I finished completing the issue. Please see my update.

[benjaminbollen]

That would likely be caused by the new opcode introduced by EIP 141 "designated invalid instruction": ethereum/EIPs#141

and indeed that is introduced as of solc 0.4.9
https://github.com/ethereum/solidity/blob/develop/Changelog.md#049-2017-01-31

it is peculiar that the returned error does not return the actual opcode (that hex string is far too long); so that is a separate issue.

Also facing same problem...did anyone resolve it??

I cannot reproduce this with solc 0.4.4, 0.4.9 or 0.4.20 - and I do not get the same payload as being sent their with transactAndHold. Will try with JS Libs
