The (compressed) crafted image which causes crash

- Overview
When mounting the attached crafted image and running program, I got this error.
Additionally, it hangs on sync after the this script.

The image is intentionally fuzzed from a normal f2fs image for testing and I enabled option CONFIG_F2FS_CHECK_FS on.

- Reproduces
cc poc_01.c
./run.sh f2fs
sync
