This seems to have begun at the below commit in bibisect repository/OS linux-64-26.2. Adding Cc: to Xisco Fauli ; Could you possibly take a look at this one? Thanks 64ac57f83881e5778032bc8e7cbae395de51bbc2 is the first bad commit commit 64ac57f83881e5778032bc8e7cbae395de51bbc2 Author: Jenkins Build User <tdf@maggie.tdf> Date: Tue Dec 30 12:19:00 2025 +0100 source 2429f04ac7d120d85e3d5eb2e679c75ccf8f0125 196313: harfbuzz: upgrade to 12.3.0 | https://gerrit.libreoffice.org/c/core/+/196313
This is an upstream issue: https://github.com/harfbuzz/harfbuzz/issues/5739
FWIW, the font is broken (it has invalid cmap table). HarfBuzz used to fix such broken fonts by altering the font data in memory, but not anymore.
