My $0.02 here: it maybe due then to other compiler options, especially 
optimizations. In non-optimized code, the compiler may produce actual 
functions (same as for static functions) even if they are marked 'inline' 
(inline is only a *hint* to the compiler, mind that). So that in debug mode, 
it produces some functions for the .cpp you were mentioning, and they are 
optimized out in the release build.  Why the linker would see these  
is unclear to me, because on Linux, it would produce a private symbol in the 
object file, hence not visible to other compilation units. On Windows, maybe 
there is no 'private' symbol, so the linker sees it, but then only in debug 
mode.

Anyway, the declaration and definition of these methods are not consistent, so 
that is the real source of the trouble and should be fixed, if you own the 
code.
