Start by comparing Corben-Regular.ttf and Corben-Bold.ttf, using the glyph-name lists in the issue to identify differences between the two files. Check the font files for the reported missing or extra glyphs and determine the intended matching set. Done means the Regular and Bold glyph sets are consistent.
