Just to amplify on what Rick said, the corner"pops" are typical, and are due to the bonding between the brick veneer and the foundation. They generally don't extend any deeper into the foundation than the brick ledge itself and are of no real consequence. The brick expands as it gets hot; the concrete doesn't want to and therefore gets pushed out at the ends. If the proper flashings are installed, this won't happen. Besides controlling water, they act as a slip joint and keep the bonding from occurring. Around here, I see very few monolithic foundations. But those I do see rarely have the details done correctly--including flashing and weep holes.
