The failure is in sp_counted_impl.hpp:66:

p is of type offset_ptr<T> and m_ptr is of type T *

Test case source, compiler output and quick fix patch (which is not fully correct, I suspect) are attached.

If you want to place the a shared_ptr in shared memory you must define a deleter whose pointer type is offset_ptr because otherwise, that shared_ptr can't be shared between processes if they map the memory in different address. You should define the deleter storing a shared_ptr. Anyway, I think you are using quite an old Interprocess version, because shared_segment_deleter does not exist currently. Download a up-to-date version from Boost SVN or the Boost 1.35 release candidate 2. Here's a link to the documentation about shared_ptr: http://igaztanaga.drivehq.com/interprocess/interprocess/interprocess_smart_p... Regards, Ion
