A huge thanks Chis, Is the bug report available on a public Sun website?
* I did try the -instances=global which gave me multiple define errors. * I can't use option 3 because I'm stuck on 5.4 for now. I haven't been able to get the first option to resolve the link problem, although it compiles. I'm using the shared pointers as member variables in my own classes. I am not defining my own namespaces. Do I need to include the namespace specifier? Sorry to have these additional questions but I'm just getting used to templates and shared_ptr is chuck full of 'em.
