Are you claiming there is a problem when FreeBSD reads such
images or a problem with creating such images?  What
programs are you using?

This sounds like a pretty unsurprising 32-bit truncation
bug:  the filesystem structures in ISO9660 are all sector
numbers so 8TB should be the natural limit (4G sectors
times 2k bytes/sector).
