The problem here lies somewhere in the generation of the accessors for Complex. We apparently cache the getattr hint for the Attributes in Complex and reuse them whenever we call the generated accessor, which results in an off-by-one error when we call the same generated accessors on a ComplexStr. Perl 6-level workaround would be to turn $.re and $.im in Complex into $!re and $!im and supplying an explicit accessor. Fixing this inside nqp-j probably involves a lot of figuring out where and how attribute hints are cached. Note that the same problem doesn't occur with IntStr or NumStr because they don't have auto-generated accessors, and RatStr gets its accessors from the role Rational, which probably gets composed differently and thus avoids the issue. I'm not sure about the details there, to be honest.
