Start with -race results in segmentation violation

[StarpTech]

Describe the bug

We wanted to upgrade from v3 to v4 and run into the following issue (no other changes has been made and rollbacking the version fix the error)

To Reproduce

The binary is not starting at all kills itself before.

[shirou]

The content of the cmd/router/main.go is unclear to us, but based solely on this error, it seems unrelated to gopsutil. Could you provide a minimal reproducible example? Also, please let us know the version of Go and gopsutil you are using.

[dmathieu]

I am getting this segfault on an ARM mac just by running the gopsutil tests with CGO_ENABLED=0 and -race.
