Reproducer is:

$ perl -Ilib -It/lib -MMoo -MMooX::Cmd::Tester -MMooX::Options -MOptionTestApp -e 'warn test_cmd(q{OptionTestApp}=>[q{--help}])->stdout;'

from the unpacked sources. It should print the usage text (that happens in F23), but it does not print anything (F25).

Scratch builds fail in koji. It also fails in local mock builds. But it passes in in weekly perl scratch builds (F25 in mock). It also passed in my F24 virtual machine until I removed all perl packaged and installed only declared dependencies.

I suspect there is some hidden undeclared dependency that causes it.

Yes. It's caused by perl-Unicode-LineBreak-2015.12-2.fc24. It fails without the package, it passes with the package.

It looks like a bug in perl-MooX-Options. /usr/share/perl5/vendor_perl/MooX/Options/Descriptive/Usage.pm has this code:

# set the column size of your terminal into the wrapper
sub _get_line_fold {
    my $columns = $ENV{TEST_FORCE_COLUMN_SIZE}
        || eval {
        require Term::Size::Any;
        [ Term::Size::Any::chars() ]->[0];
        } || 80;

    require Text::LineFold;
    return Text::LineFold->new( ColMax => $columns - 4 );
}

but perl-MooX-Options does not declare dependency on Text::LineFold.

The perl-MooX-CMD's test t/lib/OptionTestApp/Cmd/primary/Cmd/secondary.pm has some code in the eval and it's tha last common code path between failing and passing case. Just after that interpreter would open /usr/lib64/perl5/vendor_perl/Text/LineFold.pm. Because of the secondary.pm' eval the "require Text::LineFold" failure is masked so we don't get report from MooX::Options::Descriptive::Usage.
