Hello,
yesterday I had two segfaults of pcscd 1.6.7 (which I can't reproduce)
The only thing which looks suspicious is a valgrind warning.
(for 1.6.7 / 1.7.0)
"Syscall param socketcall.send(msg) points to uninitialised byte(s)"
Attached the sample program.
The valgrind warning happens with 1.7.0 too.
But I'm unsure if this is related to the segfault.
regards,
Martin
