Describe the issue

decode to a strange result of a raw transaction

Can you reliably reproduce the issue?

If so, please list the steps to reproduce below:

use bitcoin-cli decoderawtransaction 010000000001011d35c185f8bb0fe4d6f4ccfc06412040bcdce7e67614990d2eae82dc9cc5e6620000000017160014750849d2d607b9a5085a78b2a4daa5404ac3c4c2ffffffff02102700000000000017a914f7cd0db841b1da5c613194f16924ef5a3c800b1c87d354d0000000000017a914f7ef5bb0d096f5b96b7ad6d4c999d66a0776f33d870247304402203c424595c2ad559f33769d494eefedfa71d3312cb1e6fb0f64fbdbe358aaf6d602204f26789a64457e972c705757023978ed825e45a051ea07744773c6899e5bfbcd012102fa03fe77aa01b00bff222732de668f12084231e29a3dffbbd62322889afcf4a800000000

The transaction id is 89c86c5dddb4786324df8cb5a4d67537b7cf4b800e4432e3c7d60f38adb7046a

Expected behaviour

as https://blockchain.info/decode-tx show, it should be:

{
   "lock_time":0,
   "size":247,
   "inputs":[
      {
         "prev_out":{
            "index":0,

         },
         "script":"160014750849d2d607b9a5085a78b2a4daa5404ac3c4c2"
      }
   ],

   "vout_sz":2,
   "out":[
      {
         "script_string":"OP_HASH160 f7cd0db841b1da5c613194f16924ef5a3c800b1c OP_EQUAL",
         "address":"3QHGUJJzHiq2FFUnJF8MJayp6ZpmwHDKY6",
         "value":10000,
         "script":"a914f7cd0db841b1da5c613194f16924ef5a3c800b1c87"
      },
      {
         "script_string":"OP_HASH160 f7ef5bb0d096f5b96b7ad6d4c999d66a0776f33d OP_EQUAL",
         "address":"3QHyZpgKmm39371utHvQMM8WNFTRjFa7NU",

      }
   ]
}

Actual behaviour

A very large vout value is included 11337729845.69634049 which definitely is wrong.

That transaction is a witness transaction, but 0.14.2 is interpreting it as non-witness, which is why the hash is the same as the txid and there are no inputs. 0.15.0 interprets it fine.

This should be fixed in 0.15.0 by #10481
