Write a main.go, then compile it to linux x64 binary.
What did you see happen?
strings binary | grep command-line-arguments, you'll see two duplicate results. In fact, the contents of modinfo are saved twice, once in .go.buildinfo and once in .rodata, with exactly the same contents.
debug.ReadBuildInfo() uses the information in .rodata, while debug/buildinfo.ReadFile() uses the information in .go.buildinfo.
What did you expect to see?
Only save the same content once.
