新版1.2引入后会导致FMDB报错

[coolwxb]

更新到1.2之后引起fmdb初始化错误，如果将库移除了fmdb初始化就正常了

原则上与本库没有关系的。只是格式化一下打印而已啊！调用db做了些什么？代码放出来看看！

NSString* docsdir = [NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *dbpath = [docsdir stringByAppendingPathComponent:@"dituwuyou.sqlite"];
FMDatabaseQueue* queue   =[FMDatabaseQueue databaseQueueWithPath:dbpath];

到FMDB内部初始化就报错了

- (instancetype)initWithPath:(NSString*)aPath flags:(int)openFlags vfs:(NSString *)vfsName {

    self = [super init];

    if (self != nil) {

        _db = [[[self class] databaseClass] databaseWithPath:aPath];
        FMDBRetain(_db);

#if SQLITE_VERSION_NUMBER >= 3005000
        BOOL success = [_db openWithFlags:openFlags vfs:vfsName];
#else
        BOOL success = [_db open];
#endif
        if (!success) {
            NSLog(@"Could not create database queue for path %@", aPath);
            FMDBRelease(self);
            return 0x00;
        }

        _path = FMDBReturnRetained(aPath);

/*************这句崩溃了***************/
        _queue = dispatch_queue_create([[NSString stringWithFormat:@"fmdb.%@", self] UTF8String], NULL);
/******************************/
        dispatch_queue_set_specific(_queue, kDispatchQueueSpecificKey, (__bridge void *)self, NULL);
        _openFlags = openFlags;
    }

    return self;
}

和self的description有关，如 NSLog(@"%@", self); 就会出错
