When dumping classes, show where padding occurs, and at the end of the class print statistics about how many bytes total of padding exist in a class. Since PDB doesn't specifically contain information about padding, we have to mimic this by sort of reversing a small portion of the record layout algorithm (e.g. looking at offsets and sizes and trying to determine whether something is part of the same field or a new field).
