I have repeated this process a few times, always with the same error.

In one terminal,

./bitcoind -testnet

in another

./bitcoind -testnet getnewaddress

mgj4Y8AvckxborhQzqFAhppcGVGFExqJvB

./bitcoind -testnet dumpwallet /path/to/testnet3/wallet.dat

error: {"code":-1,"message":"CDB() : can't open database file wallet.dat, error 22"}

./bitcoind -testnet stop

Bitcoin server stopping

In the original terminal,

libc++abi.dylib: terminate called throwing an exception Abort trap: 6

Then I type

./bitcoind -testnet

Error: wallet.dat corrupt, salvage failed

Anybody have an idea what is going on? I updated my bitcoin to the latest on github. I also searched for the error 22 but didn't find anything. I'm guessing CDB means corrupted database. I also looked in debug.log, but I didn't see anything weird.

I know it is the dumpwallet command that is breaking it, because when I omit it from this process, nothing breaks.

The same things happens on the mainnet, altho I have not tested it as much.

Am I using the dumpwallet command incorrectly?
