--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note the quick and dirty short function testcase just includes absl and libstdc++ classes (note is not a full testcase just what I have done so far manually to testcase): ``` void BuildPolygonBoundaries() { absl::flat_hash_map<int *, std::vector<int>> children; } ``` So it is not related at all to s2geometry sources as far as I can tell.
