Are you sure you built boost with -std=c++11 correctly?

If I build libboost_python.so with -std=c++11 and then compile crashtest.cpp
with -std=c++11 it works fine, likewise building both with -std=c++98. It only
crashes when mixing c++98 library with c++11 code, or vice versa (which is
consistent with PR 53657)
