EXC_BAD_ACCESS on class GRDBDatabaseStorageAdapter sqlite at startup

[dmarras]

Hi, i'm experiencing a following issue on iOS devices up to 11.04 os version

 on line:

let code = sqlite3_wal_checkpoint_v2(db.sqliteConnection, nil, mode.rawValue, &walSizePages, &pagesCheckpointed) On 11.04 and lower no issue comes up.
