I guess it's related to the #31750 changes. The problem doesn't seem
especially platform-specific, but I've haven't seen this on my
GNU/Linux box.
The attached patch fixes it, though I'm not sure if it's
entirely correct.

Thanks for reporting that. I didn't observe the problem on Fedora 28. Anyway, I 
installed the attached patch, which should fix it.
