 Hi,

 Sorry for posting above.

 I'm reopening the ticket. This ticket appears in Boost 1.45.0 release
 notes. But seems like its not fixed yet. There are still warning messages
 with "g++ -W".

 {{{
 #include <boost/interprocess/managed_shared_memory.hpp>
 int main()
 {
    boost::interprocess::managed_shared_memory *mem;
    return 0;
 }
 }}}


 {{{
 g++ -c -W -fvisibility=hidden -g -Wall  1.cpp -o 1
 -I/usr/local/include/boost-1.45.0/
