I know it's because I'm trying to call a method on "null", but If I'm working on a huge code base, how do I debug this kind of issues if I don't have stack trace with line and error number of the error?

I'd like to get at least the stack trace and the error number with the line of the source code that caused the problem, like in golang:

  $ cat main.go
  package main
  
  type Greetings struct {
  }
  
  func (g Greetings) hello() {

  }

  func main() {
	g := &Greetings{} // heap instance
	g = nil           // intentionally shooting myself in the foot like I did in D
	g.hello()
  }
  $ go run main.go
  panic: runtime error: invalid memory address or nil pointer dereference
  [signal 0xb code=0x1 addr=0x0 pc=0x2025]

  goroutine 1 [running]:
  main.main()
	/Users/ride/Documents/main.go:13 +0x15

  goroutine 2 [runnable]:
  runtime.forcegchelper()
	/opt/boxen/homebrew/Cellar/go/1.4.2/libexec/src/runtime/proc.go:90
  runtime.goexit()
	/opt/boxen/homebrew/Cellar/go/1.4.2/libexec/src/runtime/asm_amd64.s:2232 +0x1
  exit status 2
