This is a constant point of confusion in SMILES. Clarifying it deals with this specific concern and illustrates the purpose and function of the DS.
Start by interpreting the meaning of the string c1cccn1. Run through the pruning algorithm (#41), which leaves all atoms unpruned. Finish with the error resulting from the lack of a perfect matching.
This probably best follows the discussion on pruning (#41).
