Hi @alamb. Does the cargo test (mac) run on Intel or (M1 / M2)?

I have a similar error with my M2 Air

According to https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners#supported-runners-and-hardware-resources:

Hardware specification for macOS virtual machines:

3-core CPU (x86_64)
14 GB of RAM
14 GB of SSD space

Thanks for filing this issue @HaoYang670

I recommend we #cfg this test to have the different size on ARM

Maybe with

#[cfg(target_arch = "x86_64"))]

For example

x86_64 works on my M1 Mac.
