Note, this occurs when Bitcoin-Qt is still single-threaded…

Is this reproducible? Are you running git-head or next-test? Anything special or weird about the addr.dat?

luke-jr commented at 3:03 pm on March 26, 2012: member

I can reproduce with both master and next-test by copying the addr.dat to my testnet dir. I don’t know what caused whatever is in that addr.dat triggering this.

sipa commented at 3:06 pm on March 26, 2012: member

I can’t reproduce it on master with luke’s addr.dat file.

luke-jr commented at 3:08 pm on March 26, 2012: member

Interesting. I’d be willing to share my entire testnet dir with other devs (though not the general public).

sipa commented at 3:12 pm on March 26, 2012: member

Wallet and block index are only loaded after the point that caused the backtrace above. Can you still reproduce with empty database/ dir and __db* files? If so, wallet.dat and blkindex.dat should not matter.
