We don't have much C++ code, but we should use this:

Those maintainers with C++ code which is security relevant (i.e., those programs
which are exposed to network traffic or run SUID/SGID):

please make sure the binaries and DSOs are now built with -Wl,-z,relro on the
command line when linking.  The current FC5 toolchain finally supports moving
the virtual function table into the relro sections. I.e., the function pointers
cannot be overwritten.  vtables are a big vulnerability of C++ code.
