My complete off-the-wall guess is that perl6.pbc has a :multi sub that happens to have the same name as a non-multi sub in plumhead. Or something like that. So, when perl6 is loaded first, the :multi sub in perl6 gets replaced by the non-multi sub in plumhead. When plumhead is loaded first, Parrot tries to push the :multi sub in perl6 onto the (non-:multi) sub in plumhead and throws the exception. Again, it's just a guess based on only a cursory reading of the backtraces, so don't put too much stock into it. Pm
