--- Comment #2 from James Beddek <tel...@posteo.de> ---
This turns out to be due to UB in qtspeech when compiled with Clang 13.0.0. I
have opened a relevant Qt bug report here:
https://bugreports.qt.io/projects/QTBUG/issues/QTBUG-98321
I was not able to fix it myself, though perhaps someone from KDE might be able
to :-). Below is the ubsan report:
