> The perftest scenario Mlogreg icpt 1 for 10M x 1K is failing due to unsupported cbind
in cell templates.

> The root cause is that row memo table entries are converted to cell entries due to violated
blocksize constaints, this is however not valid for cbind and similar operations that are
not supported in cell templates.
