`searchsorted` causes segfault

[dlfivefifty]

julia> using OffsetArrays

julia> o = OffsetArray([2,2,3],-1:1)
3-element OffsetArray(::Array{Int64,1}, -1:1) with eltype Int64 with indices -1:1:
 
2
 2
 3

julia> searchsorted(o,1)
Segmentation fault: 11

Using the debugger reveals its a strange bug:

julia> @enter searchsorted(o,1)
In #searchsorted#6(lt, by, rev, order, , v, x) at sort.jl:296
>1  1 ─ %1 = (Base.Order.ord)(lt, by, rev, order)
 2  │   %2 = (searchsorted)(v, x, %1)
 3  └──      return %2

About to run: (Base.Order.ord)(isless, identity, nothing, Base.Order.ForwardOrdering())

PS I want this to support offset BlockArrays: JuliaArrays/BlockArrays.jl#95

Ahhh, it's actually a bug in searchsortedfirst due to the fact that

julia> (-2) >>> 1
9223372036854775807

Let me open a second issue in JuliaLang.
