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"?

Note also the following output generated a few days ago:
I see a seg fault at exit but no infinite loop in the log. That is not
the same bug.
Can you reproduce the 100% CPU problem using "pcscd -d -f" now?
Ok, I see. Right after a suspend/resume, pcscd goes to 100% CPU. So
this is related to suspend/resume.
The output generated after the suspend/resume is:
