Slub has overwritten the object when it was freed with 0x6b. So this is an access after free. It works without debug because the object may still linger around (but there is no guarantee that the memory has not been reused). -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
