I think it's clearly main() that "owns" that error, since it's the one that swallowed it. It would be impossible for the shell to own it since it's impossible for the shell to even detect it, given this program's buggy behavior.

I find the argument that the code obviously ignores the error so that's obviously the program's intent to be completely spurious. The code "obviously" intends to print the string, too, and yet in some cases, it doesn't actually do that. It's clearly a bug. I don't think it's particularly useful to harp on this bug in the most introductory program ever, but it's definitely a bug.
