[linux-lvm] vgextend segfaults

Hai,
setup: RH7 with all updates applied
kernel: 2.4.0 and 2.4.1-pre10
LVM: tried 0.9, 0.9.1-beta1 and 0.9.1-beta2
with fdisk I created 4 primary partitions on a testdrive all
8e.
After that I do a pvcreate for those 4 partitiions:
--------------------------------
[root@water 0.9]# pvcreate -v /dev/sdb1
pvcreate -- locking logical volume manager
pvcreate -- checking physical volume name "/dev/sdb1"
pvcreate -- getting physical volume size
pvcreate -- checking partition type

[root@water 0.9]# pvcreate -v /dev/sdb2

pvcreate -- writing physical volume data to disk "/dev/sdb4"
pvcreate -- physical volume "/dev/sdb4" successfully created
pvcreate -- unlocking logical volume manager
-----------------------------------
then I do a vgscan
-----------------------------
[root@water 0.9]# vgscan
vgscan -- reading all physical volumes (this may take a
while...)
vgscan -- no volume groups found
--------------------------------------
then I do a vgcreate:
--------------------------------------

[root@water 0.9]# vgdisplay -v

--------------------------------------
Then I do a vgextend:
--------------------------------------
 vgextend -v testl /dev/sdb2

Segmentation fault
----------------------------------------
It segfaults , it segfaults whatever 2.4.0 or 2.4.1-prexxx
I use, I tried this with the above mentioned lvm's
and allways the same result. a segfault .
Now what am I doink wrong???
I tried this on two different machine one dual processor
with
adaptec 29160 adapter and one with 53c875 adapter 
both with the same disks quantum 9Gb u2w disks
TIA
