Thank you for your very swift reply and fix.
when the `-q` option is detected (grep.c:2697), the `exit_failure`
variable is set to 0. This causes any error, when not specially
handled, to exit with 0, even before any match is found.
Yes, that's a mistake. I can't reproduce your bug but I can see other
consequences of the mistake. Fixed in the attached patch (with a test
case that's unlike your problem); please give it a try.
The provided patch fixes the issue 👍
That being said, the lower levels of your OS appear to be buggy, as
'close' should not fail with EACCES. I wouldn't be surprised if other
software breaks because of this issue. So I suggest also reporting a
bug to whoever maintains the NFS client code that you're using.
I'm aware. I'll try to look into it, but it seems like a much deeper
rabbit hole.
Thanks again,
Jan
