Is it possible for a Go program to experience a stack overflow?

Yes, in Go, a stack overflow situation is possible, although the language uses a dynamically growing stack for goroutines. Each execution thread (goroutine) starts with a small stack (usually a few kilobytes), which automatically expands if necessary.
However, if recursion is too deep or there is an infinite function call, the stack can grow to its limit, resulting in a panic with a stack overflow error.
Example causing a stack overflow:
func recurse() {
recurse()
}
func main() {
recurse()
}
In this example, infinite recursion will lead to a stack overflow and crash the program.
Thus, despite dynamic stack management, overflow is possible with excessive stack usage.
