What did you do?

Do go build or go test with Goland 2024.3 on Mac M1 normally.

What did you see happen?

panic: unexpected 32-bit segment

What did you expect to see?

I just want to share the solution for people searching

command execute:

go env -w CGO_ENABLED='0'

and set cgo support disable in Goland Setting

do you have code that can reproduce this issue?
is this reproducible without goland?
which clang is used?
