Hello

I want to seal and unseal data against some PCR: 4, 8, 9 and 12.

But, when I'm user or root, it segfaults:
r...@darkstar:~# echo -n s3cr3t | tpm_sealdata -z -p4 -p8 -p9 -p12 -o seal
(it hangs here for about a minute, then:)
Segmentation fault
r...@darkstar:~#

What can I do? I reset the TPM chip from the BIOS, taken owneship of it,
reboot several times.
I can access my PCR through /sys/class/misc/tpm0/device/pcrs

Any idea of what's happening?
r...@darkstar:~# dmesg | grep tpm
tpm_tis 00:0d: 1.2 TPM (device-id 0x1001, rev-id 2)
tpm_sealdata[3712]: segfault at c ip b7e8ec4e sp bfcac300 error 4 in
