Subject: [R-pkg-devel] gcc-san fail with s2 package
I am trying to get a new version of a package; however, the gcc-san test
failed:
/usr/include/absl/container/internal/raw_hash_set.h:4052:56: in
?constexpr? expansion of
?absl::debian7::container_internal::hash_policy_traits<absl::debian7::container_internal::FlatHashSetPolicy<s2shapeutil::ShapeEdgeId>,

ERROR: compilation failed for package ?s2?
* removing ?/home/hornik/tmp/CRAN_special_gcc-san/Library/s2?
Since my package isn't directly dependent on this one (it's fourth order),
I'm not sure how to proceed. Actually, I was surprised by this ERROR with a
package that is on CRAN.
