You need a colon after dup.

But this can't possibly be a dup of that bug. That bug was fixed in February:
https://syzkaller.appspot.com/bug?extid=93a5839deb355537440f

And this crash happened a day ago. This is a different bug. If you dup
it to a closed one, this one will also be considered closed, and then
a new crash will immediately create a new bug.
