There are quite a few hacks that MSVC uses to get C++ code to live well in
DLLs (ok, some of these are rules, but the rest are truly hacks!), and GNU
C++ compiler has yet to incorporate some of these. Examples include vtable
emission rules.

btw, unless you provide correct and complete code that shows the problem,
I typically just ignore it. Feel free to send me minimal code, preferably
tar-gz'd/zipped, that shows the problem.
