We haven't really dealt with assignment of non-Perl 6 types until now. In this case it was treating the UnManagedStruct as a scalar value, and thus it tried to copy the PMC instead of creating a reference to it. In r32873 I've updated assignment semantics so that it now tries to do the right thing when dealing with something coming from outside Rakudo's type system. In particular, assigning an UnManagedStruct to a scalar value should now properly take a reference instead of attempting to do the copy. Let us know if it helps. Pm
