How often does it reproduce? Is there a required condition?
I have only tried it on Linux. Since overlapped is intended for Windows, the behavior might differ there.
This only crashes with spawnSync(), not spawn().
What is the expected behavior? Why is that the expected behavior?
This should either behave like pipe, or throw an error. I am not sure which behavior would be the best there.
What do you see instead?
The process crashes.
