[leonardt]

Can you try running it with pytest -s? This should prevent pytest from capturing stdout, and may give us some more useful information to see what the error is.

[1]    55634 bus error  pytest -s

[leonardt]

Hmm, I wonder if this is related to python3.9. I don't think we've tested that, could you try downgrading to python 3.8 and see if you still get the same error. Also, are you using a local build of coreir? Or are you using the version distributed with pip? We should first try to see if the pip release works, then we can look into what's going on with the local build. If the pip version isn't working then there is something to investigate there.

[shi27feng]

I was building with a local one since I am sure that the pip one is not supporting apple m1 architecture.

[leonardt]

Hmm, I think I may need to find access to an M1 VM to debug since there's not enough info here to see exactly what's going on. If possible, you could try running with lldb (e.g. lldb -- pytest) then run bt and post the backtrace, this might give some more info on where in the code it's running into an error.
