[J3] Is it standard conforming to index a zero-sized array?

[Daniel C Chen]

Is the following code legal?

integer, allocatable :: arr(:)
allocate(arr(0))
arr(5) = 1          !! Is this line legal?
end

I understand a zero-sized array is always defined and it can be used as LHS
of an assignment. But is it legal to indexing it?
I seems can't find any specific rule about it in the standard.

Thanks,

Daniel Chen
