Getting Started example not working on macOS 11.3, Apple M1 chip #44

Hello, people.

I just wanted to let you know that at least the Getting Started example doesn't seem to be working on macOS 11.3, Apple M1 chip, whereas it works correctly on my old machine, which is an Intel Macbook Pro running macOS 10.15.7.

If I print the size of int, float, and double types, I get the same results on both machines (4, 4, and 8).

This is the output when I try running the Getting Started example on BigSur:

dariosanfilippo@Darios-MBP kann % seq 30000 | awk -v m=10000 '{a=int(m*rand());b=int(m*rand());print a,b,a+b}' \
  | ./examples/rnn-bit -m7 -o add.kan -

dariosanfilippo@Darios-MBP kann % echo 400958 737471 | ./examples/rnn-bit -Ai add.kan -

Would you know what the issue might be?

Thank you so much for your help.
