Can not reproduce bugs with ubuntu 18.04 and back-port LKL kernel 4.16 about hydra HOT 2 OPEN

Hi, I was wondering how did you fix your second Screenshot error message? Does fuzzer aborted the orginal hydra image f2fs after 10 hours 45 minutes?
I got assertion error on Program.cpp line 254, Any idea how to handle or fix such errors?

Hi, @junchoi999 i didn't fix it. It might come from my setup. Because as you see, i didn't reproduce bugs presented in the SOSP'19 paper.
Did you saw the bugs?

Thanks for your reply. No, I did not find any bug either from original image fs. Not sure what could be the reason.

About the error, do you think its because of the setup? I was trying using a new image fs tho, did you try with a new image fs as well to test it? . @jiyangyangyangyang

Hi @junchoi999 what do you mean by new image fs? I currently trying to use ubuntu 22.04 and kernel lkl v5.10.
You also can not reproduce the bug? That is so strange, Any idea why? I use a VM u18.04, kernel 5.0.0-23-generic and lkl(hydra-lkl) v4.16-backport.
