Greetings, I would like to request a review of the Shifted Pointer utility. I am happy to say that I've corrected some bugs within the library itself and now it seems to be working well with all test files. As pointed out by John Maddock, some pool functions such as ordered_free() can still be optimized in speed or replaced but for now I would like to keep the interface as it is until perhaps some changes to the pool can be proposed. Once again to compile the test executables (with gcc): $ svn co http://svn.boost.org/svn/boost/sandbox/shifted_ptr $ cd shifted_ptr/libs/smart_ptr/example $ make shifted_ptr_test3 And its documentation can be found here: http://fornux.com/personal/philippe/devel/shifted_ptr/libs/smart_ptr/doc/ Regards, -Phil
