title: Stack trace of go routine from imported package?
body: <p>How to obtain the stack trace of the last (ideally of all) go routine (the app has multiple go routines) which panicked and recovered and logged only a not much descriptive error message? I don't know which routine recovered. Also, please keep in mind that I will not alter the code of any imported package. This panic happened in some of the imported packages which creates multiple go routines so I need a way to grab the stack trace of the last recovered routine in order to find where it panic.</p>
