GnuPG with pcsc-lite, scdaemon segfaults

[Simon Ferber]

Hello list,

I installed an fresh amd64 system with gnupg and smartcard support.
When pcsc-lite is started, I can see following in the logs:

As you can see, it find the reader and recognises the insertion of an card.

Well, no matter, which options I give to gnupg, I get an segfault in the
logs:
Mar 29 20:52:43 [kernel] gnupg-pcsc-wrap[21763]: segfault at 0 ip
0000000000000000 sp 00007fffc815e0d8 error 14 in
gnupg-pcsc-wrapper[400000+87000]



Or when I try to start scdaemon, it segfault again:
ray ~ # scdaemon  --debug-all --pcsc-driver
/usr/lib/libpcsclite.so.1.0.0 --server
scdaemon[21766]: Optionen werden aus '/root/.gnupg/scdaemon.conf' gelesen
scdaemon[21766]: Handhabungsroutine für fd -1 gestartet
Speicherzugriffsfehler



I tried several versions of gnupg and pcsc-lite. But always it
segfaults. :-/

Any idea? Oh, btw, now I use:
Kernel 2.6.28
gpg 2.0.11
libgcrypt 1.4.4
pcsc-lite 1.4.2

I ran out of ideas...

Kind regards,
Simon
