That's not what i see in my experiments.
I see stuttering output which first repeats the lines put out so far
before it adds a new line.
The getline() loop iterates as often as there are input lines.

The fact that you report input woes matches tom kronmiller's reported
remedy of setvbuf(stdin, NULL, _IONBF, 0).
So maybe i see something completely different than both of you.
Will make more experiments.


Have a nice day :)
