fsck_ufs dumps core

[Dmitry Sivachenko]

Hello,

I am running FreeBSD 10.3-STABLE #0 r299261M

After unclean reboot I am unable to fsck my UFS filesystem:

# fsck  /dev/mfid0p1
** /dev/mfid0p1
** Last Mounted on /opt
** Phase 1 - Check Blocks and Sizes
fsck: /dev/mfid0p1: Segmentation fault

pid 482 (fsck_ufs), uid 0: exited on signal 11 (core dumped)

# gdb -c fsck_ufs.482 /sbin/fsck_ufs
