> try `cmake .. -DCMAKE_CXX_FLAGS="-O2"` This avoids the crash by reducing optimization level and skipping problematic vectorization. Neither the compile flag `-DCMAKE_CXX_FLAGS=-O2` nor `-DCMAKE_CXX_FLAGS_RELEASE="-O2 -DNDEBUG"` works for me.

I followed steps 5 and 6 mentioned on [this page](https://www.bijanbowen.com/bitnet-b1-58-on-raspberry-pi-4b/) instead of running `setup_env.py`, and it works.
