Description Antonin Godard 2026-01-15 09:55:57 UTC 
I got this error on a master-next test build, and it's mixed with llvm failures that at this time I knew was due to a faulty patch[1]. However this fontconfig failure seems unrelated to llvm. Create an AB-INT to see if this happens again on master.
