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?
