Hm we really need a way to map addresses back to symbols on win32, otherwise stack traces are very unhelpful :/ ... with the deterministic build it should be possible to save the debug symbols, but I don't know enough about win32 to be able to resolve them.

I built the source & debugged it in Qt, crash occurs on the dbenv.open call, db.cpp line 92. Found the below in the debug.log, presume my db file is out of date. Perhaps the dbenv.open call should be in a try/catch.

EXCEPTION: 22DbRunRecoveryException
DbEnv::open: DB_RUNRECOVERY: Fatal error, run database recovery

Deleting the bitcoin directory didn't work, now it throws on pdb->open, db.cpp line 113

Does bitcoind fail in a similar fashion?

Yes, same problem, Unhandled exception at 0x76549966 in bitcoind.exe: 0xC0000005: Access violation reading location 0x01b774b4.

Does this problem still exist with the newest version?
