How would you use the debug.PrintStack() function in Go?

The debug.PrintStack() function in Go is used to print a stack trace of goroutines. When called, it generates a stack trace that shows the sequence of function calls and their execution paths across goroutines in your program. This can be extremely useful for identifying where your program is encountering issues, such as deadlocks or panics. By examining the stack trace, you can pinpoint the location in your code where the problem occurred and gain insights into the call chain that led to it. This is essential for diagnosing and troubleshooting concurrency-related problems in Go programs.
