That's puzzling - if you applied the changes correctly, at least the
error message should have changed slightly.  I don't see how it can be
"cmp_one(1)" in there (notice the "1") with the changed code.

I understand the error message changing is a "nothing" for your actual
usage, though.

You can also try building an older revision of JtR:

git checkout bb82d0153bafc3e52a53f64c69809a563bbc47ba

or if that doesn't help, even older:

git checkout f59129c8b77032dabaf407d73f95e4394a62fe9e

These specific revisions correspond to moments just before relevant
changes to zip-opencl were made in our codebase, so using these
revisions is likely to hide the issue you're running into (but may
expose other issues, including bugs we've since fixed, unfortunately).

These are an alternative to the manual edits I had suggested (that is,
don't make any manual edits when trying these older revisions).

You'll need to:

./configure # maybe with options
make -s clean
make -sj24

after each "git checkout".  You don't need the complicated approach with
two builds and OMP_FALLBACK_BINARY that you've been using (although it
does not hurt, and you can use it if you like).
