[comment by blelbach] [Trac time Fri Aug 26 00:29:52 2011] Bah. Standard says we're wrong - temp.class.spec, paragraph 1, last sentence:

A partial specialization shall be declared before the first use of a class template specialization that would make use of the partial specialization as a result of an implicit or explicit instantiation in every translation unit in which such a use occurs; no diagnostic is required.

This is a problem in a handful of places. MSVC doesn't detect this. GCC 4.5 and older don't diagnose this, either.

[comment by blelbach] [Trac time Tue Sep 13 15:35:45 2011] This needs to be reported upstream to Boost.Atomic/Boost.Lockfree.
