Incorrect display

julia> using RecursiveArrayTools

julia> RecursiveArrayTools.ArrayPartition{Tuple{Vector{Float64}, Vector{Float64}}}(([0.0499001, 0.0995482],[0.497004, -0.0090711]))
RecursiveArrayTools.ArrayPartition{Tuple{Array{Float64,1},Array{Float64,1}}} with arrays::
   0.0499001
   0.497004 
 #undef

The incorrect display can lead to segmentation fault when bounds check is off.

-> % julia -q --check-bounds=no
