You were because ... | I recompiled r-cran-rcpp and libquantlib0-dev with GCC 6, instaled | them and rquantlib built with GCC 6. ... that is as expected while ... | | I then went back to r-cran-rcpp and libquantlib0-dev from the archive | (built with GCC 5), built rquantlib with GCC 6 and it failed.

I guess the general rule is to, if in doubt, rebuild with the same compiler. OTOH all the g++-5 pain to set us up for a smoother transition. Maybe we're not there yet.
