--- Comment #5 from Theodore Tso (tytso@mit.edu) ---
I assume LKL is "Linux Kernel Library", so this is trying to run the ext4 file
system executing the system calls found in poc-01.c in userspace?

Are there instructions so we can build the ext4_combined from source?  That's
going to be needed if we are going to be able to run the binary under a
debugger, and versus a patched kernel to verify the fix.

Also, can you give us a stack dump so we might have some kind of hint what's
going on?
