The regex/locale failures on apple platforms are unrelated - most likely due to an OS update (if we don't fix it soon we'll XFAIL the tests). The android failures should be fixed in trunk I think, but are also definitely unrelated. You can consider the CI green if no other failures in any future runs. If you're not sure feel free to ping me.
