OK, after a complet download from the official torrent ... no crash of this version 0.9.3 on my WinXP SP3 + all KBs updates.
Strange that it have been located on the blockchain files

So, the answer is : when bitcoin core crash without warning ... re-download the whole blockchain folder.
ps : i don't have changed anything in this computer ... and it's run only for network stuff (no private use).
That's strange indeed. Probably a database (either the UTXO database or the block index) was corrupted in a sneaky way. You had tried a reindex before?
Anyhow, great to hear that your problem is solved.
I am very curious to know when CoinJoin might be incorporated as something fully supported and available from Core, and given recent concerns regarding state actors such as the Russian Federation or some proposals which have recently come out of the UNSC, I believe that it would be timely to clarify this issue and raise its priority.
It will be incorporated when someone implements it. It's an open source project, so there is no saying who will pick this up. AFAIK no one is working on wallet features in Bitcoin Core at the moment. The core developers are focused on improving the node infrastructure. Maybe Cozz (who got Coin Control to a state where it could be merged) would be interested, given incentive.
Thanks for your reply. I am not sure what would be the best way to communicate with Cozz to relay my thoughts or request. Please advise by private message in this forum if possible.
Again, thanks.
