Error in unsafe_convert on nightly

julia> Base.unsafe_convert(Ptr{Float64}, OffsetArray(zeros(2)))
ERROR: conversion to pointer not defined for Vector{Float64}

This is related to JuliaLang/julia#51962. I wonder if @chriselrod might have time to submit a fix? I'm unsure what the recommended method is in this case.
