Hm, looks like the proprietary library has some issues, but also does gnutls: (proprietary library warnings about uninitialised values skipped) Object 0: URL: pkcs11:library-description=Cryptographic%20Token%20Interface;library-manufacturer=A.E.T.%20Europe%20B.V.;model=3384110107000000;manufacturer=A.E.T.%20Europe%20B.V.;serial=00113C3800009B09;token=Fraunhofer-Smartcard;object=Secude%20Token%20ID;object-type=data Type: Data Label: Secude Token ID ==19018== Invalid read of size 1 ==19018== at 0x4E653CF: _gnutls_bin2hex (gnutls_str.c:443) ==19018== by 0x4E75D41: pkcs11_get_info (pkcs11.c:409) ==19018== by 0x40424D: pkcs11_list (pkcs11.c:193) ==19018== by 0x403750: main (p11tool.c:135) ==19018== Address 0x0 is not stack'd, malloc'd or (recently) free'd ==19018== ==19018== ==19018== Process terminating with default action of signal 11 (SIGSEGV) ==19018== Access not within mapped region at address 0x0 ==19018== at 0x4E653CF: _gnutls_bin2hex (gnutls_str.c:443) ==19018== by 0x4E75D41: pkcs11_get_info (pkcs11.c:409) ==19018== by 0x40424D: pkcs11_list (pkcs11.c:193) ==19018== by 0x403750: main (p11tool.c:135) ==19018== If you believe this happened as a result of a stack ==19018== overflow in your program's main thread (unlikely but ==19018== possible), you can try to increase the size of the ==19018== main thread stack using the --main-stacksize= flag. ==19018== The main thread stack size used in this run was 8388608. ==19018== ==19018== HEAP SUMMARY: ==19018== in use at exit: 551,735 bytes in 1,892 blocks ==19018== total heap usage: 14,940 allocs, 13,048 frees, 8,311,394 bytes allocated ==19018== ==19018== LEAK SUMMARY: ==19018== definitely lost: 4 bytes in 1 blocks ==19018== indirectly lost: 0 bytes in 0 blocks ==19018== possibly lost: 288 bytes in 1 blocks ==19018== still reachable: 551,443 bytes in 1,890 blocks ==19018== suppressed: 0 bytes in 0 blocks ==19018== Rerun with --leak-check=full to see details of leaked memory ==19018== ==19018== For counts of detected and suppressed errors, rerun with: -v ==19018== ERROR SUMMARY: 34 errors from 15 contexts (suppressed: 25 from 7) Killed > Could you also try whether that issue occurs in gnutls 3.0.14?
