Comment (by rrobgill):

However, the block numbers in the panic are both in the 2TB range, but
 one of them shows as negative which makes me think we have just a signed
 vs unsigned error somewhere.

 Exfat's Directoryiterator.h has fOffset as signed, compared to unsigned in
 other filesystems with similar usage. But it also explicitly assigns
 negative values to fOffset.
