how to catch stack overflow error in golang

Question

Is there any way to catch stack overflow error in golang? Currently I'm using go recover() do this job(below code snippet), looks like stack overflow error can't be caught.

defer func() {
            if x := recover(); x != nil {
                log.Error("In recover, cought error====================", x)
            }
        }()

fn(xxx)

What you see in the output is a "fatal error", not a panic.

fatal error: stack overflow

You can only use recover() to recover from panics. A stack overflow is a fatal error thrown by the runtime which causes the process to print a stack trace and exit.
