Validate Failure On OSX -- implicit fall through error for machO linker support (master == ghc8.5)
seems like validate for OSX needs some TLC, heres a bug from the linker code that maybe could use an eyeball or two. Phyx suggests someone familiar with the code base could simply do
__attribute__ ((fallthrough));
, which is allegedly also supported by clang?
