The conversion of
```
func @extract_dims(%arg0: !fir.box<!fir.array<*:f64>>) -> index {
%c1 = arith.constant 0 : i32
%0:3 = fir.box_dims %arg0, %c1 : (!fir.box<!fir.array<*:f64>>, i32) -> (index, index, index)
return %0 : index
}
```
to the LLVM dialect produces IR that accesses a struct with invalid index (7 for a struct of 7 elements),
This code was present in the `convert-to-llvm.fir` test. https://github.com/llvm/llvm-project/commit/301226562b28088b112651cadf6695eba1e2ef87 disabled it as it triggered assertion in MLIR.
