I happen to have counterfeit such an ISO back in 2018.

  $ src/iso-info -i "$isodir"/multi_extent_8k_w_gap.iso --iso9660
  ...

One of the extents of multi_extent_8k.iso had been patched to claim
one block less than written by the manipulated libisofs. This gap between
the end of the fourth extent and start of the fifth triggered the warning.
Looks good.

I seem never have to reported about that ISO or uploaded it.


Have a nice day :)
