Title:
  LVM2 snapshot merge error report: "lvm crashed with SIGSEGV in
  lv_is_merging_cow()"

Status in lvm2 package in Ubuntu:
  New

Bug description:
  Xubuntu 14.04.4 LTS
  SSD is only drive (/dev/sda)
  /dev/sda1 is boot partition
  /dev/sda5 is encrypted LUKS partition
  logical volumes sit on top of the LUKS partition

  package: lvm2 2.02.98-6ubuntu2
  problem type: Crash
  title: lvm crashed with SIGSEGV in lv_is_merging_cow()

  This bug is repeatable. If I create a LVM snapshot of lvroot (mounted
  to /) and run lvconvert --merge to restore the snapshot, after
  rebooting, this error report is generated.

  However, if instead of running lvconvert --merge inside the system, I
  boot into a live ISO session and run lvconvert --merge, the process
  completes without any error being reported.
