 fuzunspm - Please take a look at the fix applied to redis in

 https://github.com/macports/macports-
 ports/commit/e35f356df49a71148c38f8531b08b8a4abee926b#diff-
 c863911924e8a4d3140f5648ae95de02

 patches similar to that have had to be applied to a number of ports now,
 to work around the issues we have with Xcode 11's clang.

 If you are willing to try doing the leg work yourself, please try applying
 a similar fix to mono to see if it also addresses the issues here ?
