Empty shared_ptr_nmt returns use_count() = 1

[B van den Hout <smork1@…>]

If you construct an empty shared_ptr, the use_count() method will return 0. This is indicated in the documentation as "Postconditions: use_count() == 0 && get() == 0."

If I look at the implementation in boost/smart_ptr/detail/shared_ptr_nmt.hpp, the default constructed shared_ptr will create a count_type(1). That means that use_count() will return 1 even if I construct it without any initial value. This is inconsistent IMHO.

Yes, I suppose it is. shared_ptr_nmt.hpp (nmt - no member templates), however, is no longer used by any of the compilers with which Boost is tested.

If there is not a real test case we should close the ticket.

I propose this ticket should be closed indeed. The explanation that this is a no longer tested/used version of shared_ptr is sufficient for me. Your development time is probably best spent on the more recent version. Thanks for the acknowledgement though :)
