cmd/link: Go 1.4.2 ldflags -s still shows the line numbers of the stack trace

What platform did I use for test:

Microsoft Windows 7 x86 , go 1.4.2 windows x86

What code did I use for test:

// test
package main

func main() {
    panic("golang")
}

What command did I use for complier the test program:

go build -ldflags "-s -w" test.go

What am I expected to see :

Should not print the line number in the stack trace.

What exactly did the complier show:

panic: golang

goroutine 1 [running]:
main.main()
        D:/Users/lenovo/Desktop/test.go:5 +0x54
...

So... Is it designed to always shows the line numbers ?

There may be security reason that some projects may needs to hide or strip some unexpected printing messages. So I just curious 😄

-s does not strip line number information.

-s is not tested and is not recommended as it is know to produce broken executables on multiple platforms.

OK , I get it . I think this should be add into the golang document , as I was looking for some ideas to block the whole debugging messages
