@TIFitis From the IR that you pasted, it looks like `    %5 = "fir.shape"(%0) : (index) -> !fir.shape<1>` is dependent on `  %0 = "arith.constant"() <{value = 1024 : index}> : () -> index` that is created outside the region.

I believe the lowering code did not have to deal with `IsolatedFromAbove` regions before, so it might be reusing values. So while you are seeing this in HLFIR code, it is not necessarily an HLFIR issue. We can discuss this in the call today.
