Arguments Overflow in encodeABI

[melnikaite]

c = new web3.eth.Contract([{"constant":true,"inputs":[{"name":"a","type":"bytes32"},{"name":"b","type":"bytes32"}],"name":"bIsWrong","outputs":[{"name":"","type":"bytes32"}],"payable":false,"type":"function","stateMutability":"view"}])

c.methods.bIsWrong('a'.repeat(64), 'b'.repeat(64)).encodeABI()
returns
0x020e2724aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
which is fine

c.methods.bIsWrong('a'.repeat(65), 'b'.repeat(64)).encodeABI()
returns
0x020e2724aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa000000000000000000000000000000000000000000000000000000000000000bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
which is wrong, because second argument gets wrong value a000000000000000000000000000000000000000000000000000000000000000

Expected behaviour is raising error, because first argument exceeded length of specified in ABI type

Good catch, if you like you can raise a PR to enhance input type checking.

Should be fixed in the next release.
