      Wrapper object use after free

      A use after free bug would occur if the internal pointer is used. An internal pointer of a wrapper object remains available after the object is freed
      /src/mongo/db/timeseries/bucket_compression.cpp:279: WRAPPER_ESCAPE 121223 Calling "get" which extracts wrapped state from local "tamperedData".
      /src/mongo/db/timeseries/bucket_compression.cpp:281: WRAPPER_ESCAPE 121223 The internal representation of local "tamperedData" escapes into "measurements.front().timeField", but is destroyed when it exits scope.
