    Description

      Plz see my last comment int MCOL-5310 to get the idea of what happens.
      dataconvert::strtoll128 gets count() as a widedecimal column and its precision is 9999. The precision is used as an index in an array of 38 elements thus it is either out-of-bounds access and SEGV is called or a unexpected math result.
