Segmentation fault (core dump) with btrfsck and btrfs restore

[d4l3k]

I'm having issues with btrfs and btrfs-progs. I've tried using an older kernel 3.9 and 3.13 as well as compiling btrfs-progs from git.

I'm on my phone and I couldn't tee the core dump for some reason. Here's some pictures.

Background:
My laptop started acting really weird and x crashed. Systemd started spamming messages about failing to write because the filesystem was read only. Nothing would respond. I force powered it off and btrfs says it has a bad block. Booted it up with a livecd and tried to fix it according to help online. Noticed segfault.

Also, S.M.A.R.T. checks passed, and the partition is encrypted with dm-crypt.
