    // MADlib aligns the pointers returned by palloc() to 16-byte boundaries
    // (see Allocator_impl.hpp). This is done to allow Eigen vectorization  (see
    // http://eigen.tuxfamily.org/index.php?title=FAQ#Vectorization for more
    // info).  This vectorization has to be explicitly disabled if pointers are
    // not 16-byte aligned. Further, the pointer realignment invalidates a
    // header that palloc creates just prior to the pointer address.  Greenplum
    // after commit f62bd1c fails due to this invalid header.  Hence, the
    // pointer realignment and Eigen vectorization is disabled below for
    // Greenplum 6 and above.
