A cavity wall

This is a typical cavity wall seen from the above. The problem lies in a nature of this two materials.  New, dry brick irreversibly expands during the first year after production.  The opposite process takes place in a concrete, which shrinks and creeps under dead load.
There are also some reversible thermal, moisture related and structural movements, which create, stresses and make this assembly restless.
All those factors shall be taken under consideration and brick shall be kept mechanically separated from concrete in such a way that the tightness and the structural connections are kept.

This photo shows that there is a visible mortar bridge on the right side of cavity. I anticipate the crack would form between two portions of the brick veneer: the bridged one and the free one.
Also the mortar protrudes from brick bed joints and the head brick joints are not filled completely.  The thaw-freeze cycles of water running and saturating brick veneer would cause freeze cracks and spalling.
