Formatting lost for specific object

[stevenroose]

I've had this issue since always in one of my projects. The newlines and indentations get lost when using spew on a certain object type. All other object both before and after dumping this one, are printed just fine.

This is the type definition and all the subtypes. It can be found in the wild here: https://github.com/ethereum/go-ethereum/blob/master/core/types/receipt.go#L46

type Receipt struct {
    PostState         []byte
    Status            uint
    CumulativeGasUsed *big.Int
    Bloom             Bloom
    Logs              []*Log
    TxHash            common.Hash
    ContractAddress   common.Address
    GasUsed           *big.Int
}

type Hash [HashLength]byte
type Address [AddressLength]byte
type Bloom [BloomByteLength]byte

type Log struct {
    Address     common.Address
    Topics      []common.Hash
    Data        []byte
    BlockNumber uint64
    TxHash      common.Hash
    TxIndex     uint
    BlockHash   common.Hash
    Index       uint
    Removed     bool
}

It looks like some of the values are breaking for formatting.

Here's an example:

(spew.ConfigState) {
 Indent: (string) (len=1) " ",
 MaxDepth: (int) 0,
 DisableMethods: (bool) false,
 DisablePointerMethods: (bool) false,
 DisablePointerAddresses: (bool) false,
 DisableCapacities: (bool) false,
 ContinueOnMethod: (bool) false,
 SortKeys: (bool) false,
 SpewKeys: (bool) false
}
(*types.Receipt)(0xc420001c80)(receipt{status=0 cgas=3500000 bloom=00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 logs=[]})
(spew.ConfigState) {
 Indent: (string) (len=1) " ",
 MaxDepth: (int) 0,
 DisableMethods: (bool) false,
 DisablePointerMethods: (bool) false,
 DisablePointerAddresses: (bool) false,
 DisableCapacities: (bool) false,
 ContinueOnMethod: (bool) false,
 SortKeys: (bool) false,
 SpewKeys: (bool) false
}

Whoops, just remember that I had this issue a year ago and that it was the String() method that looks a lot like spew output.
