Yes, this would cause error in the titration,
More HCl will be required in such a case.
In the molecular formula of Calcium Hydroxide there will appear to be more than 2 OH- ions. More HCl would be required for titration which would mean the presence of more OH- ions. So formula would be something like Ca(OH)x where x>2.
