Database releaseReadLock exception

[Victor Fernandez]

Hi
Sometimes I'm getting the exception CBL_FMDatabase releaseReadLock in the method createDatabase of the CBLDatabase object (iOS Framework). This is the log that I was able to see in crashalytics:

Fatal Exception: NSInternalInconsistencyException

Too many calls to releaseReadLock

11	KomandApp	HCAppDelegate.m line 136 -[HCAppDelegate application:didFinishLaunchingWithOptions:]

Does anyone have an idea of why this could be happen?

Regards!

I was going to suspect threading problems in app code, but it looks like the app just launched and hasn’t even finished opening the database yet, so that seems unlikely.

I don’t know what could cause this. The locking code around SQLite is pretty solid, and I’ve never seen this particular crash before. Can you reproduce this yourself, or does it only happen in the field?

Please file a bug report. Make sure to include the version of CBL.

Where I need to make the bug report? In github?
