Comment (by k-bx):

 Just wanted to mention that a direct application of a patch on top of
 8.2.2 (with some conflict resolution done) doesn't work for me and I'm not
 experienced enough to understand what's going on
 https://gist.github.com/k-bx/9b4a3d95f2de9c86b50dca1c615c63e6

 I first cherry-picked the commit, but then tried manual change-by-change
 cherry-picking, getting same error on three machines (1 macOS, 2 Ubuntu).

 I guess my another attempt would be to see if building
 5124b04f10adfee6390f435a493984f2b45062d0 itself as a replacement for our
 8.2.2 will be a good idea.
