I'm having problems in my 'release' build of my project when linking with boost::serialization. The only real difference between my 'debug' and 'release' build is I defined DEBUG and use -O0 in debug and I defined NDEBUG and use -O3 in release.
I can compile, link and run totally fine in debug mode.
However, when I compile with release mode, it will compile fine but fail during linking with the following error:

I don't understand this, as the methods in question are fully defined. I don't do any sort of #ifdef NDEBUG, etc. macros in my code in these classes.
Does anyone understand why this might happen?
My Texture2D class:
Texture2D.hpp
Texture2D.cpp
My TextureManager class:
TextureManager.hpp
TextureManager.cpp
I'm happy to give more direct/localized code snippets if that would help.
Update: If I move the definition for the serialize methods into the header files, suddenly it links! I imagine this has to do with them being template methods, but I still don't understand why my 'debug' build works but my 'release' build doesn't...
