What if you change that code to add a bit more offset? The code adds 1e-10f (-200dB) to the input of the first delay element in a 2nd order allpass filter. How much of this remains at other points depends on the filter parameters, but it won't go much below -230dB. And that is giant overkill already. Denormals for 32-bit FP are below -750dB.
