    Description

      The following sequence causes mysqld to crash at dbcon/execplan/calpontsystemcatalog.h:303. It appears the rhs has bad data and is probably already deleted.

      select count(distinct idbPm(l_orderkey)) from lineitem;
      <runs for a very long time>
      After a second, cancel with ctrl-c

      select min(idbExtentRelativeRid(s_suppkey)), max(idbExtentRelativeRid(s_suppkey)), min(s_suppkey), max(s_suppkey) from supplier;
      <crash>
