I just realised you have an Apple silicon, you can try two merge ocl_array from Termux and Apple silicon file on my site together. I will try to make a new release for all platforms except old Intel-based Mac.

Hi, dear all
To Marius,
to your question: This was a problem due to the initialization position. You can give ocl-1.2.0-Termux.tar.gz a try on my project site if your system is with Octave 8.4.
https://sourceforge.net/projects/octave-ocl-extra/files/ . I have reported the error to the original author Matt.

To Dmitri, there should be no error with 9.1. Meanwhile, I also reported the " ocl_array.h:277:9: warning" to Matt at least one year ago, that this will cause a seg fault problem with AMD GPU platform. I guess Matt was busy and missed my info. I have this fixed on my project site.

Best wishes,
Jinchuan

FWIW, on linux with octave 9.0.1 I see:
