Hi, Thank you for the bug report. To resolve the issue, I need the font file causing the crash. Could you post it as well ? To find it, you could for example add a print statement to textprocessing/fontconfig.scanOneFontFile.

By the way, this module has been superseded by go-text/typesetting : you should use it instead if possible.

I've fixed the bug in the upstream textlayout repo.
