It also eats lots of memory. 스크린샷, 2020-03-02 16-35-40

I found the issue. Order is important.

1:38 <- 0:10
1:41 <- 0:13
2:9 <- 0:10
2:12 <- 0:13
3:44 <- 0:10
3:48 <- 0:13
8:23 <- 2:21
8:27 <- 2:25

works while

1:38 <- 0:10
2:9 <- 0:10
3:44 <- 0:10
1:41 <- 0:13
2:12 <- 0:13
3:48 <- 0:13
8:23 <- 2:21
8:27 <- 2:25

does not.

Format is (dst <- src)
