Hello, I'm on NixOS and we recently updated a libreoffice dependency `icu` to 70. <https://icu.unicode.org/download/70> When building libreoffice 7.2.2.2 with `--with-system-libs`, it builds successfully but fails exact one unit test. > /build/libreoffice-7.2.2.2/i18npool/qa/cppunit/test_breakiterator.cxx:865:TestBreakIterator::testLao > equality assertion failed > - Expected: 9 > - Actual : 12 I can confirm that downgrading `icu` back to 69.0 fixes the test failure. But I'm not sure what is this test doing and I cannot read Lao. Does the test need updating, or there it's an issue of the new `icu` 70.0? I also notice that the `testLao` is currently guarded and only be enabled if icu >51. Does it depends on some icu behaviors and we should also exclude it for icu >=70? The full log of build and test can be seen here, <https://hydra.nixos.org/log/zwqzj8n84z4kb8nscch815kypn4x6m9c-libreoffice-7.2.2.2.drv> Thanks, Oxalica
