"Illegal instruction: 4" error on macOS-latest runner

[chidiwilliams]

Running the binary on the Mac build:

            - name: Test
              run: |
                bash models/download-ggml-model.sh tiny
                ./main -m models/ggml-tiny.bin -f samples/jfk.wav

...raises the following error:

4062 Illegal instruction: 4  ./main -m models/ggml-tiny.bin -f samples/jfk.wav

I haven't yet been able to track down what line/function the error comes from, but I am fairly certain it was introduced by https://github.com/ggerganov/whisper.cpp/commit/ac521a566ea6a79ba968c30101140db9f65d187b.

Thanks for reporting this.

I agree it's possible, but would be nice if we can confirm that.

It might be useful to add cat /proc/cpuinfo before building the project to see some information about the CPUs that the MacOS Github runner is using. Also, I just added some extra prints to the Makefile in 0be6a1afd9d6e7848ffc5917c2a66a3cd4eba53e - might give us some extra clue.

The CPU does not support FMA. I believe this should be fixed now thanks to 322f4e6c4ea8f8b3526bb6cebce0113cd157fe62

[chidiwilliams]

Works, thanks.
