Just to close the loop on this:
This happened when:
You ran version 0.3.17, and sent/received some coins
You then ran an earlier version, and the coins you sent/received with 0.3.17 were rewriten to the wallet (e.g. you spent them or they got included in a block). They'd get rewritten incorrectly (marked as version 0.3.17, but missing extra info).
... and then you upgraded to version 0.3.17 again. Bitcoin would crash trying to read the extra, missing info.
svn r196 fixes the problem, by storing the extra account info in a different way and detecting the badly-written 0.3.17 entries.
Topic: Incompatible wallet format with latest bitcoin-git ? (Read 2091 times)
As far as i remember i just used an svn checkout patched with m0ms getwork.
I've made a mass save of all my wallets and replaced them by new ones, i just plan on using them against an older version of bitcoins in a couple of months to check if coins arrived to one of them and then send them to my new wallets.
I haven't seen any half-done accounts patch around, just built from git source when gavin announced the functionality on the forum.
Anyway, if I'm the only one impacted it's a non-issue

Was there an interim version of accounts on git at some point that had just ("acentry", "account") for the key?
I just browsed back through the git commit history, and I don't see any interim commits of the account code (I was working in local branches, and didn't push interim versions up).
davout: You should try dumping your wallet using the latest bitcointools (dbdump.py --wallet), it will tell you if it finds weird key values in there.
What was this wallet used with? An early accounts patch or git build?
It's while loading the wallet. I assume it must be in this:
else if (strType == "acentry")
{
string strAccount;
ssKey >> strAccount;
uint64 nNumber;
ssKey >> nNumber;
if (nNumber > nAccountingEntryNumber)
nAccountingEntryNumber = nNumber;
}
You could check that with this:
else if (strType == "acentry")
{
string strAccount;
assert(!ssKey.empty());
ssKey >> strAccount;
uint64 nNumber;
if (ssKey.size() != 8 )
printf("***** %s %d\n", strAccount.c_str(), ssKey.size());
assert(ssKey.empty() == false);
ssKey >> nNumber;
if (nNumber > nAccountingEntryNumber)
nAccountingEntryNumber = nNumber;
}

If you have gdb, you could run it in gdb and do a backtrace.
gdb --args bitcoin ...
run
(wait for exception)
bt

I have tested accounts, it works very well
Hi all,
just built the latest bitcoin-git source, seems like the wallet or database format has changed

Could it be 84d7c981dc52cc738053 that broke something ?

What are the lines in debug.log leading up to the end-of-file exception you pasted?
I haven't tested my 'master' bitcoin-git branch in a while, I wouldn't be surprised if the new 'accounts' code in the subversion tree broke something.
Which not-in-subversion features are you using?
