The check of LLVM was done two years ago, and the bugs found then were fixed. This article will show a new portion of errors. :) https://www.viva64.com/en/b/0629/
I think we can resolve this specific bug, the highlighted issues (and the other instances of the same issue alluded to in the article) have been addressed. In general though, PVS-Studio still finds a lot of issues in the codebase [Bug #30996].
