Dear Maintainer,
Hello,
Since a few weeks, pcscd has been using 100% CPU, as shown by 'top':

I put this bug as grave because it affects the machine as a whole,
feel free to change it to suit your needs.
I will need more debug information.
Can you:
1. run pcscd inside gdb
I have a problem here:
(gdb) run
Starting program: /usr/sbin/pcscd
warning: Could not load shared library symbols for linux-vdso.so.1.
Do you need "set solib-search-path" or "set sysroot"?
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
[Inferior 1 (process 7795) exited normally]
(gdb)
Note also the following output generated a few days ago:

2. stop pcscd using Ctrl-C while in the 100% CPU loop
3. use the "bt" gdb command to generate a backtrace
4. send the result
5. kill any running pcscd
6. run in a terminal "sudo pcscd -dfa"
7. send me the result
