            Bug ID: 110636
           Summary: boost::geometry compile error with std::set.
           Product: gcc
           Version: og12 (devel/omp/gcc-12)
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: justin at jtcholzer dot net
  Target Milestone: ---

At work, we ran across this upgrading from GCC 9 to GCC 12.
This is a trivial example.  In our large code base we use a "unity build" that
mixes including of .h and .cpp files to speed linking.  We worked around the
issue by removing "using std::set;" from all files.
