Each time I run "bitcoind listaccounts", I see the following in the debug log.  Does it indicate corruption somewhere in my ~/.bitcoin/ files, or is this an issue for everyone?  I'm running "Bitcoin version v0.7.1-dirty-beta".

I assume you are mining in a pool that directly shares the outputs of the coinbase transaction with the miners?

It looks that those txid are for coinbase transactions (which have no previous unspent transaction for the input):

Interesting - at the top of both of those tx's the following appears on blockchain.info:

Unable to decode input address (followed by a small BTC amount)

and looking at the "Output Scripts" the script for the above reads as this:

Code:
OP_IFDUP OP_IF OP_2SWAP OP_VERIFY OP_2OVER OP_DEPTH

Strange indeed. Smiley

There is another "unable to decode output" at the end of the list (with 0 BTC which perhaps makes more sense as being some sort of message to "identify" the mining pool?).

With CIYAM anyone can create 100% generated C++ web applications in literally minutes.

I'm not mining at all.  I did CPU mine at P2Pool for a couple of weeks when I first found out about it, so that could be it.

Basically, when listtransactions runs, it looks at every output of every transaction that you are involved in, even the outputs that are not yours.  This causes these messages to show up in your logs, because p2pool uses a bogus txout for internal pool tracking.

See here and here.

That's pretty much it, although FWIW the particularly odd scriptPubKey posted above, "OP_IFDUP OP_IF OP_2SWAP OP_VERIFY OP_2OVER OP_DEPTH", was actually created by an old bug in P2Pool where one of the scriptPubKeys was being set to the data "script" rather than a proper serialized script. The "OP_IFDUP" etc. happens to be what that string decodes to in op-codes. The bug has been long since fixed, but the OP did mention they mined at p2pool some time ago.

Thanks.  That's reassuring.

I keep switching between client versions 0.7.x and 0.8.x and thought maybe that had corrupted something.
