Use DUMP_PREFIX_OFFSET when printing hex dumps of corrupt buffers because modern Linux now prints a 32-bit hash of our 64-bit pointer when using DUMP_PREFIX_ADDRESS: 00000000b4bb4297: 00 00 00 00 00 00 00 00 3b ee 00 00 00 00 00 00 ........;....... 00000005ec77e26: 00 00 00 00 02 d0 5a 00 00 00 00 00 00 00 00 00 ......Z......... 000000015938018: 21 98 e8 b4 fd de 4c 07 bc ea 3c e5 ae b4 7c 48 !.....L...<...|H This is totally worthless for a sequential dump since we probably only care about tracking the buffer offsets and afaik there's no way to recover the actual pointer from the hashed value.
