I saw similarly bogus sector (block) numbers when I first debugged this problem. They were caused by missing prototypes. 32-bit block numbers were passed to unprototyped functions that expected daddr_t block numbers. When daddr_t was changed to 64 bits, there was garbage in the top 32 bits. dump doesn't compile cleanly at a high WARNS level, so now would be a good time to WARNSify it.
