I stand corrected. It *is* Mac OS X compiler bug.

It seems to be a common problem which is related to using pure virtual
method in a constructor or destructor, see here:

The fix in this case is to inline the copy constructor. I'm currently
testing a patch which do that (only under Mac OS X to avoid breaking
the binary ABI).
