The issues is: you are trying to concat an `intbv`
and a `long`.  A `long` doesn't have a length so the
concat doesn't work.  You end up with a `long` when
you do the decrement `addr-1`.  This operation
results in a `long` not a type with a length.

I created a minimal example to demonstrate the `concat`
works with the large bitvectors:
