    Description

      If the coarsest level of the geo 2dsphere index is set >= 27, it will result in an assertion error in S2 on certain points. This is caused by https://github.com/mongodb/mongo/blob/master/src/mongo/db/query/expression_index.cpp#L113 which does not enforce that 4 + coarsestLevel <= 30.
