Minimised: https://go.dev/play/p/oL17vkcjaEl
This is happening because the sum in a doesn't result in a
normalisation of b, https://go.dev/play/p/cIBDbRXFnAT (in this
situation where the abs field represents a zero, it should be zero
length).
Given that this can happen without a race or unsafe modifications it
might be worth filing a issue for.
