it appears to be a problem with 'zero' semantics:

The problem is that a 0-length write does not extend the size, but a 0-length zero is changing the object size.

@Kefu Chai: Changing the #21818 link to "Related" instead of "Copied" since I'm guessing #21818 is a separate bug; not a backport?

@Nathan Weinberg, thanks for fixing this. i didn't realize that "Copied" implied "backport", i just used "copy" as a handy tool to create a new bug.

i didn't realize that "Copied" implied "backport"

Copy is used to make the backport tracker issues, and sometimes it's done manually and the person doing it forgets to change the tracker (of the copy) from Bug to Backport. That was my assumption when I saw you had copied, but then I looked closer and realized you were creating a new bug. So yes, the copy function does imply a backport, but probably just for me, so don't let that stop you from using it :-)
