g++ refrains from folding in expressions which appear as template
arguments.  I don't know whether that is right or wrong.

However, this case is not in a template argument, so I don't think
that arguments about folding apply here.

In any case, I am hardly a C++ expert.  If anybody has a better
suggestion for how to demangle _ZN2BBcvPFivEEv, I'm happy to hear it.
