LoadError: BoundsError: attempt to access 2-element Vector{LoopVectorization.ArrayReferenceMeta} at index [0]

Hi,

I am working with Julia v1.6.2 with LoopVectorization v0.12.166. I am new to LoopVectorization, and I cannot figure out the problem after searching online for quite a while.

Here is a MWE of the error that I encounter.
```
using LoopVectorization
function test(a, b)
@turbo for i in axes(a,1)
a[i, 1] = 0.0
for j in axes(a,2)
a[i, 1] += b[i,j]
end
end
return nothing
end

a = rand(256, 256)
b = rand(256, 256)
test(a, b)
```

will give me ($HOMEFOLDER is used below for privacy)

However, if I remove the line `a[i, 1] = 0.0`, it works well. The original also works if I don't use `@turbo`.

Could you help me understand this error message? And how should I implement such a task using `@turbo`? Thanks very much!
