Pete Batard's MinGW-w64 complained:

I should have put brackets around the computation.

Argh. A residue from a test.
I assume that valgrind did not complain because the compiler inserted some
padding in struct iso9660_statv2_s between
(My question about alignment issues got no answers or opinions yet.)
I tried to correct the flaws by commit 2d58119

No need to do so.
I recognized the size problem early, but decided to go on in order to offer
a true choice between your proposal and mine.
Part of the changeset's complexity is the deplorable state of inner
architecture in current iso9660_fs.c and rock.c. Insofar, iso9660_statv2_t
would be a real improvement.

If it would be the way to get access to large files, then the pain would
be the price for progress.
The effort is not unbearable (i'd offer help to users) and the runtime
check should detect any incomplete transition work.

Yeah ! Accepted because of its big sad eyes ... :))
Have a nice day :)
