I found other two cases which caused Segmentation Fault.

# lvcreate --version
  LVM version:     2.02.61(1)-cvs (2010-02-02)
  Library version: 1.02.44-cvs (2010-02-02)
  Driver version:  4.16.0

Tests are done with lvm2, 2.02.61(1)-cvs (2010-02-02) with this
patch set, and vg00 contains just one PV.

[case 1]
# lvcreate -m1 -L12m -nlv00 --mirrorlog mirrored --alloc anywhere vg00
Segmentation fault

[case 2]
# dmsetup table
vg00-lv00: 0 24576 linear 8:32 384
# lvconvert -m1 --mirrorlog mirrored --alloc anywhere vg00/lv00
Segmentation fault

In both cases, initialization of log_areas array seems to have a problem.

Thanks,
Taka
