ERROR: LoadError: KeyError: key :zeroB not found #15

Description

@chrisvwx

Using LoopVectorization.jl#master, I get the following error. I'm not certain how to describe the error, so I put part of the error message in the issue name. I tried a few small variants, with the same result. Is it somehow obvious that I should not put B[i,j] inside the k loop? It works fine without the @avx macro.

julia> using LoopVectorization
julia> function myGramFail!(A, B)
           zeroB = zero(eltype(B))
           @avx for i ∈ 1:size(A,1), j ∈ 1:size(A,2)
               B[i,j] = zeroB
               for k ∈ 1:size(A,2)
                   B[i,j] += A[i,k] * A[k,j]
               end
           end
       end
