case.c, file operations to reproduce the bug

I have encountered a bug in F2FS file system.

I created a disk image and modified some properties. After that, I mount the
image and run some commands related to file operations, and the bug occurs.

The file operations are in the "case.c" file, and a modified image named
"case.img" can be achieved from
(https://drive.google.com/file/d/1--eGC9FZW4aXt35kjpKwUp5k6k1qIpcx/view?usp=sharing).
You can reproduce the bug by running the following commands:

gcc -o case case.c
losetup /dev/loop0 case.img
mount -o
"background_gc=sync,disable_roll_forward,nouser_xattr,disable_ext_identify,nobarrier,fastboot,mode=adaptive,grpquota,noquota,alloc_mode=reuse,test_dummy_encryption"
-t f2fs /dev/loop0 /root/mnt
./case

The kernel message is shown below:
