[boost] [pool] segfault

I was testing my own "shifted_ptr_test2.cpp" on RHEL 4.5 using Gcc 3.4.6 and the following object declared in "sh_owned_base_nt.hpp" caused a segmentation violation inside its destructor. It doesn't seem to happen on Windows, just Linux: pool owned_base::pool_; // derives from boost::pool<> Thanks, -Phil
