The modifiers are u_vectors, but the code was trying to access them
as dynarrays. This resulted in a wrong number of modifiers, which then
later on would also lead to invalid reads used as modifiers.
In the case of the iris driver, a wrongly read number of modifiers > 0
would also trigger an error message.
