Right, I missed that one.

Chances are some recent tweaks, even the empty initializer list, triggered
that again for the member. Just ignore it (even with #pragma
warning(disable:4251)
in your code).

I recommend avoiding this in the first place - putting STL types in
your DLL's interface
forces you to play by the STL's rules (specifically, you can't mix
different major versions
of VC, and your IDL settings must match).
However, there is a workaround. C4251 is essentially noise and can be
silenced...
