Thanks for pointing this out. I dismissed this issue because it this
situation the "back" pointer doesn't refer to the first element in the set
list after several insertions and this creates a series of problems which
may have a solution but better left aside for this type of problem.

I added some code in shifted_ptr::release() which will make it disregard any
reference count when the destructor is called upon a set deletion. Now
everything works fine.
