It is possible to cause a panic by calling
TxIn::pegin_dataon a malformed pegin, which has 6 entries and the last one (which should be a Merkle proof of block inclusion) is too small to even have a blockhash in it.On the actual chain this should not be possible because invalid pegin data would be rejected.
