clang-8 prints these and other warnings:

All those warnings (and several additional ones) should be fixed in current stable branch.

Thanks for the heads up!

aferrero2707 commented 4 years ago

There are no more warnings with clang from Apple LLVM version 10.0.1, therefore I am closing the issue.
