Regarding returning multiple values from the goroutine, two possibilities come to mind. Does the returned value from the goroutine is getting stored on stake. However this is a new stack which is destroyed when the goroutine ends so there is no possibility of retrieving the return value.

Does the returned value from the goroutine is getting stored on stake. You don't even have guarantee it was called from your function, it may be called to initialize a global variable for example. Inside your doStuff() function, myCoords is already a pointer. So when it is called from a goroutine, it does store its results to the stack.
