In addition to name mangling, calling convention and other issues accross
compilers, C++ presents problems with ABI incompatibility even when using the
same compiler.  If your library is designed with user-extensible classes,
choosing C++ places severe constraints upon core development -- no new virtual
methods or member variables in non-leaf classes, etc:

The comment thread here may be germane (it describes some of the reasons we
avoided C++ for Apache Lucy):
