Dear maintainer, I encountered an issue using pcsc-lite and libusb on Ubuntu 10.04 LTS. Now and then libusb segfaults and causes pcscd to crash.
The error occurred with libusb-1.0-0 (1.0.8), so I updated libusb-1.0-0 and libusb-1.0-0-dev to 1.0.11 (libusbx) a few days ago, hoping the issue was fixed meanwhile. Unfortunately it happened again. I tried to reproduce the failure on my testing environment while pcscd was running in gdb, but I was not able to trigger it. The only output I'm able to provide: [syslog – libusb 1.0.8] kernel: [358812.500109] show_signal_msg: 18 callbacks suppressed kernel: [358812.500124] pcscd[907]: segfault at 8 ip 00fd12f8 sp b6f2b030 error 4 in libusb-1.0.so.0.0.0[fcd000+d000] [syslog – libusbx 1.0.11] kernel: [144649.500131] show_signal_msg: 9 callbacks suppressed kernel: [144649.500144] pcscd[898]: segfault at 8 ip 00fbfac8 sp b6f02030 error 4 in libusb-1.0.so.0.1.0[fbb000+e000] The pcsc-daemon loads at startup by executing the start script /etc/init.d/pcscd. Any help or advice will be appreciated. Thank you very much in advance. --------- Regards Sebastian ========= Ubuntu 10.04 LTS Linux 3.0.0-17-generic #30~lucid1-Ubuntu SMP Fri Mar 9 15:10:54 UTC 2012 i686 GNU/Linux pcsc-lite version 1.8.3.
