While the release works for me on Fedora Linux distribution, it consistently
fails on Red Hat Enterprise Linux 7 distribution. The only failure is the
French locale test 3. Maybe the locale definition differ. I don't know the
exact casue yet.

The test 3 fails on non-jit UTF-8. The testtry output should match
./testdata/testoutput3A, but it does not:

The older pcre2-10.20 passes. I bisected the failure to this commit:

    Tidied up a lot of comments in the test files.

Indeed this expression /[[:lower:]]/IB,locale=fr_FR returns different result.
I only cannot explain how the commit triggers the change because I cannot see
any relevant change.

I will try to digg futher.
