FMDB崩溃*** -[FMResultSet retain]: message sent to deallocated instance 0x604003a49e70

执行FMDB语句时候，偶尔会发生崩溃 信息如下

*** -[FMResultSet retain]: message sent to deallocated instance 0x604003a49e70

代码很少

__block NSArray *arrs = [NSArray new];

        [jqFmdb jq_inDatabase:^{

            __strong typeof(weakSelf)strongSelf=weakSelf;

            arrs = [strongSelf ->jqFmdb jq_lookupTable:[NSString stringWithFormat:@"qunDetail%@",strongSelf.chatCreateSuccessEntity.groupId] dicOrModel:[ZJContact class] whereFormat:[NSString stringWithFormat:@""]];

        }];

在此代码上面还有其他FMDb操作 但是都在线程安全block中，僵尸断点在FMDB库中FMResultSet *rs = (FMResultSet *)[rsInWrappedInATastyValueMeal pointerValue]; 具体定位到这一行

#ifdef DEBUG

            NSSet *openSetCopy = FMDBReturnAutoreleased([[db valueForKey:@"_openResultSets"] copy]);

            for (NSValue *rsInWrappedInATastyValueMeal in openSetCopy) {

                FMResultSet *rs = (FMResultSet *)[rsInWrappedInATastyValueMeal pointerValue];

                NSLog(@"query: '%@'", [rs query]);

            }

#endif

        }

    });

    

    FMDBRelease(self);

请问哪位好心人帮帮忙看看呢，用着用着就能崩了 哎
