I'm not sure why this doesn't work. I have the exact same pattern for addresses and it does fine.
bytes32[] public someStorage; function addToStorage(bytes32 someData) { someStorage.push(someData); } Then using web3:
instance.addToStorage("Some Data", {from: web3.eth.accounts[0], gas:1000000}) I get a tx address but in testrpc console I see a matching Runtime Error: Invalid Opcode and it always consumes the max gas that I set.
