smart_ptr_test still fails.  I compiled with

g++ -I ../../.. -D_REENTRANT -pthread -g -o smart_ptr_test 
smart_ptr_test.cpp

The gdb output is

(gdb) run

I grabbed the CVS instead of using the 1.33.0 package I was working with 
before.  I assume this was what you intended?

As an aside, do I gather correctly from the presence of "-D_REENTRANT 
-pthread" the smart pointer code is multithreaded?  Anything I write 
using smart pointers, regardless of whether or not my code is 
multithreaded, will require the flags?
