crash FMDBBlockSQLiteCallBackFunction #414

Closed gongtao closed 8 years ago

gongtao commented 8 years ago

I used FMDB in private dispatch_queue blocks, and received crash logs. I did not use any functions that contain FMDBBlockSQLiteCallBackFunction function. I used [FMDatabaseQueue inDatabase:] function to access database.

Crashed: com.xiaomi.micloud.sdk.contact.queue EXC_BAD_ACCESS KERN_INVALID_ADDRESS at 0x0000000000000000

Well, something is calling it - com.xiaomi.micloud.sdk.contact.queue. Looks like a 3rd party SDK
