String decoding breaks

[montyanderson]

Decoding a name() returns (string) breaks.

  Error: Number can only safely store up to 53 bits

This was actually due to passing in a string to abi.rawDecode and it failing silently.

Possible we should check that the data argument is definitely a buffer?

Same problem actual for me:

const inTypes = [
    'address',
    'address',
    'address',
    'address',
    'uint256',
    'uint256',
    'uint256',
    'uint256',
    'uint256',
    'uint256',
    'bytes',
    'bytes',
    '[]',
    'uint256',
    'bytes[]'
];

const input = '0000000000000000000000000000000000000000000000000000000000000060000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000002e0000000000000000000000000000000000000000000000000000000000000000100000000000000000000000000000000000000000000000000000000000000200000000000000000000000006924a03bb710eaf199ab6ac9f2bb148215ae9b5d0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000a258b39954cef5cb142fd567a46cddb31a67012400000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000002ce954ae8b5d1cf0000000000000000000000000000000000000000000000036c090d0ca6888000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000005d15e7c50000000000000000000000000000000000000000000000000000016b9d8e9ab2000000000000000000000000000000000000000000000000000000000000018000000000000000000000000000000000000000000000000000000000000001e00000000000000000000000000000000000000000000000000000000000000024f47261b0000000000000000000000000c02aaa39b223fe8d0a0e5c4f27ead9083c756cc2000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000024f47261b000000000000000000000000089d24a6b4ccb1b6faa2625fe562bdd9a23260359000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000421b01fda954331f6f5430d93ab7a884458b4b5259e6ce2127e3c41a6090d10481375023f3c61afb372349ec0ecbd0e476593cce90cc8dbb46cf569875910753705403000000000000000000000000000000000000000000000000000000000000';

abi.rawDecode(inTypes, Buffer.from(input, 'hex'))

It seems I wrongly parsed argument types:

marketSellOrders((address,address,address,address,uint256,uint256,uint256,uint256,uint256,uint256,bytes,bytes)[],uint256,bytes[])
