Thank you for the new patch.
I installed the patch (after reverting the previous one) and pluto does not
crash anymore as well. An "ipsec listcards" is working as well and shows three
certificates.

Hi Rene,

No. As far as I can see, this only happens if multiple certificates are
stored with the same ID on one smartcard. That's the only case the
added certificate object is act
Great.
Could you try the attached patch (after reverting the previous one).
This should fix the root cause of the problem.

Thank you. Pluto is not crashing any more. I still can't connect to the
VPN, but this might be a configuration problem. I will try to solve this
on myself. If you have any other patches, I should check, you can attach
it to the message.

Thanks.
The cause of this segfault seems to be how pluto handles the storage of
two certificates with the same ID.
>From your log:
| found cert in slot: 1 with id: 46, label: 'Verschluesselungs Zertifikat 1'
...

I started pluto as following: /usr/lib/ipsec/pluto --nofork --stderrlog
--debug-all 2> /tmp/pluto.txt

Thanks for the backtrace. It is indeed a different bug.
>From the backtrace it looks like the list of certificates somehow gets
corrupted.
Could you attach the log output with "plutodebug=all" set in ipsec.conf.

I tried to start pluto in gdb. The result is the following:
Program received signal SIGSEGV, Segmentation fault.
0x003141cc in equals (this=0x80e7188, other=0x0) at x509_cert.c:1248
1248if (other->get_type(other) != CERT_X509)
(gdb) p other
$1 = (certificate_t *) 0x0
(gdb) bt
#0 0x003
I tried to install the fix, but still get a segfault.
I'm not sure, that it's the same segfault as described in the patch, as, if I'm
not mistaken, the log indicates the segfault happens in libstrongswan-x509.so
