I'm certainly concerned about issues such as #593876 where the stricter linking breaks existing code. I'm not sure about the rationale for this extra strictness, but it does cause unwanted breakage by breaking existing assumptions about indirect linking. Other than that, it's working fine for me. It would be nice to have in the release as an optional and non-default compiler for developers who need it. Regards, Roger -- .''`.
