Sundtek Support Forum

Hallo,

ich habe gestern versucht, den neuesten Treiber mit den virtuellen Demotreiber (mediaclient --tvdummy) zu testen. In dem Rechner steckt zur Zeit kein USB-Stick, aber eine Hauppauge PVR250 PCI-Karte.

Dabei stürzt mediasrv mit einem SIGSEGV ab. Ein ltrace auf den mediasrv-Prozess zeigt, dass strncpy mit einem NULL-Pointer als Argument aufgerufen wird:

24548 strftime("2011-11-29 08:31:08", 200, "%Y-%m-%d %H:%M:%S", 0xb7736700) = 19
24548 getpid()                                   = 24544
24548 fprintf(0x84b6018, "%s [%d] ", "2011-11-29 08:31:08", 24544) = 28(siehe mediasrv.log im Anhang)
24548 vfprintf(0x84b6018, "registering ID: %d\n", 0xb64292e8) = 18
24548 fflush(0x84b6018)                          = 0
24548 pthread_mutex_unlock(0x8078310, 0x8072c25, 0xb64292e8, 24544, 0) = 0
24548 strncpy(0x084b6974, NULL, 100 <unfinished ...>
24548 --- SIGSEGV (Segmentation fault) ---
