@cmb69 After some troubleshooting, it seems that our issue was due to the first flag, CPU
optimizations. When enabled, CPUs with the
avx instruction set, but not
avx2 or avx512..., exhibited segfaults when running JIT. It may be
worthwhile to see why this is occurring, but it would be more appropriate for us to open a separate
issue at some point in the future.
