bitcoin-qt.exe fatal error - NSt8ios_base7faillureE - ReadCompactSize()

[nanpanman]

When running the windows client 0.62 I get the following error shortly after the ''Loading Block Index...' screen:

A fatal error occured. Bitcoin can no longer continue safely and will quit.

Running 0.62 on Win7, can send debug.log over if needed.

Your blk0001.dat or blkindex.dat file got corrupted somehow (did you run out of disk space perhaps?). To recover, backup your wallet.dat file, remove everything except for wallet.dat from the bitcoin data directory, and re-run.

Keeping this bug open, because it would be good to at least report a helpful error message in cases like this, and even better if bitcoin could recover itself. Pieter and Mike have both been working on complete re-writes of the block database, though, so spending time working on the current way we're doing things might be a waste of time.

Thanks Gavin.

This error has been happening to me every couple of months going back to maybe September 2011. I've always upgraded to the latest version hoping the bug would be gone (including clean re-installs) but for some reason I always comes back. It is a pain since the only way to recover is to delete all the block-chain files and re-download. My wallet was never affected though.

I don't think I ran out of space (although space is tight - I'm running on a 64GB SSD). Perhaps it has to do with the fact that I always send my laptop into 'sleep' mode while running the bitcoin client in the background?

Good to hear a rewrite of the block db is on the way. Sounds like that might fix the issue.

Speaking of the devil - the bitcoin client just unexpectedly crashed on me again. I have 5.54GB Free space on my SSD.

I am able to restart the client without errors this time though, so it could be unrelated/different bug.

@nanpanman still got the problem?

[nanpanman]

No. I moved to a new computer no issues since. The previous one had an SSD
that got progressively more corrupted so that might have been the culprit.
