I've updated to bitcoincore 0.17 and I'm trying to create a raw transaction to be signed on an offline wallet.

I'm creating a raw transaction with createrawtransaction with no inputs and the desired outputs. With the hex generated I'm using fundrawtransaction to match inputs.

Since the online wallet is watch only I need to pass includeWatching as params. Also I want to send the change amount to a different address, so I add changeAddress the the options hash. This kills the entire bitcoind process with no warnings and no log messages

This is the commands I've tried and their output:

$ bitcoin-cli createrawtransaction '[]' '{"14XbnUUvc2Kt8TrnnEG9zjF1XM2jYD1h8x":0.001}'
020000000001a0860100000000001976a91426b1e477be0f7bc5e2cf12dd5b973e57e7fab5bf88ac00000000

$ bitcoin-cli fundrawtransaction 020000000001a0860100000000001976a91426b1e477be0f7bc5e2cf12dd5b973e57e7fab5bf88ac00000000

Make sure the bitcoind server is running and that you are connecting to the correct RPC port.

How can I see the error that killed bitcoind? Am I doing something wrong?

UPDATE

After using GDB I've found that this is the problem:

bitcoind: policy/feerate.cpp:25: CAmount CFeeRate::GetFee(size_t) const: Assertion `nBytes_ <= uint64_t(std::numeric_limits<int64_t>::max())' failed.

Thread 7 "bitcoin-httpwor" received signal SIGABRT, Aborted.

Any hints?

  • That's a strange error, not sure if this will help, but what OS are you on, and how did you install bitcoind? – JBaczuk Nov 1 '18 at 19:20
  • Sorry, forgot to add. I'm using ubuntu 18.04, i've installed via apt-get. Also, if you know how to downgrade bitcoind it should work too – Nicos Karalis Nov 1 '18 at 19:22
  • You can download and install whichever binaries you want to your system folders from bitcoincore.org/en/releases – JBaczuk Nov 1 '18 at 19:33
  • That's what I wan't. But I'm not that good with ubuntu. Can you point me a guide to install binaries? – Nicos Karalis Nov 1 '18 at 19:48
  • Depending on which version your downgrading to, all you need to do is replace the binaries that you want (probably bitcoind and bitcoin-cli in /usr/local/bin or wherever they are installed (try running $which bitcoind to find where they are). – JBaczuk Nov 1 '18 at 19:56

This is a known crasher in 0.17.

You need to either:

  • downgrade to 0.16.3
  • apply the patch given in the pull request and build Bitcoin Core yourself
  • wait until 0.17.1 is released to fix the issue.
