It seems the quotes aren't being put in the right places when  
constructing
"$stub" and "$non_lazy_ptr" names, they should look like this:

"L(complicated<expression>)$non_lazy_ptr"

with the quotes outside.  This hasn't come up before because the only  
places quotes
occur now is in ObjectiveC names which don't use stubs or non-lazy  
pointers.
I guess it ought to work, though, shouldn't be hard.
