Eligius has some anti spam rules so instead of trying to create a zero value output why not add a second inputs so all the outputs are above the dust threshold and txn has the standard min fee.

I've tried various output/fee amounts (but without adding an extra input), including fees of 0.00008192, 0.0001, 0.0002, and 0.001536 (the whole amount). I'm pretty sure that I've met any tx fee and dust requirements Eligius might have, including all of the public rules at http://eligius.st/~gateway/faq-page.

I was the one that submitted https://blockchain.info/tx/ce7d73cba662af3dfbd699384111115f4ccd24b3748a88bf9bc70c1cc4d08660 to Eligius, which has a smaller total input than this transaction, and was accepted without an issue with a 0.0001 fee.

Also, this transaction is very small, at only 132 bytes, so anything that takes size as a factor should rank this very favorably.

OP did you create the tx that you are now trying to spend? Testnet is better to help you avoid losing btc

I'm aware of Testnet, though I've never bothered to do anything with it.
I created ce7d73cba662af3dfbd699384111115f4ccd24b3748a88bf9bc70c1cc4d08660, which is a simple anyone-spend script (it's zero-length) worth only 0.0001, see this thread talking about it: https://bitcointalksearch.org/topic/why-wont-core-send-this-transaction-686214
After seeing this remained unspent for several days, I wondered if there were any other anyone-spends out there, and ran across this other tx that I'm trying to spend, worth ~1.4 mBTC=~$1. I did not create it, and I realize I'm spending more in time than I'll actually get as a reward for spending it to myself. Just doing it out of curiosity.

Eligius alerady contains spending tx in its memory-pool
Double-spending attempt causes generic -22 error

UPDATE: not confirmed.
Eligius (either web-form or 68.168.105.168:8333) does not accept this spending transaction.

Nope, not that easy: Eligius would've entered that into the blockchain by now, but both txouts are still unspent.

Does anyone know of a way to have Bitcoin Core try to validate the transaction? Maybe Eligius's validator doesn't implement the alt stack correctly.

Blockchain.info says 'Unable to decode output address' for the output address, which, in my experience means that the output address is not an address that has an associated private key, meaning it is not spendable.

There is no such thing as an output address. Outputs are scripts and blockchain.info is pretty bad at decoding all but the most basic and standardized scripts.

I think that it's valid. Try paying a higher fee.

That's not it: even if I reduce the output to 0 so the fee is 0.00153600 BTC, Eligius rejects it with the same generic error:

Code:

Trying to send...
array(3) {
["result"]=>
NULL
["error"]=>
array(2) {
["code"]=>
int(-22)
["message"]=>
string(11) "TX rejected"
}
["id"]=>
string(1) "1"
}
Response = 0

OP_DROP

I think this script should be able to spend it:

Code:

OP_TRUE OP_TOALTSTACK
2 5 6

Entering the scripts at http://webbtc.com/script seems to agree with me. I formed this transaction to spend it and another anyone-spend, but it's being rejected by Eligius (despite including a suitable tx fee).
Here it is in raw format

Code:

01000000026086d0c41c0cc79bbf888a74b324cd4c5f1111413899d6fb3daf62a6cb737dce010000000151ffffffffaf73ff160d0434f1d8da871552ba06b1c24af1e91b494b2f4cbe25457eb973430000000005516b525556ffffffff0100380200000000001976a914cb1f2f015ddbe2aeffceb1652b26ee424fd0c2f288ac00000000

And in Bitcoin Core's JSON encoding

Code:

Is this transaction valid or invalid? If it's valid, why does Eligius reject it? Is there any pool that will take it? If it's invalid, why?
