My package 'secr' has been throwing WARN on r-devel-macos-arm64 in CRAN's check results for at least a week or two. It's fine on other systems.
A typical message from the log is -
In file included from /Volumes/Builds/packages/sonoma-arm64/Rlib/4.6/RcppParallel/include/tbb/internal/_concurrent_unordered_impl.h:37:
/Volumes/Builds/packages/sonoma-arm64/Rlib/4.6/RcppParallel/include/tbb/internal/../atomic.h:226:18: warning: volatile-qualified parameter type 'const volatile long long' is deprecated [-Wdeprecated-volatile]
Does this need attention? The CRAN warning is not an immediate problem, but might block my next revision.
