Comment (by clord@…):

 It's not a compiler bug. The bug is in the example code (load_impl and
 save_impl in portable_binary_iarchive.hpp and portable_binary_oarchive.hpp
 respectively). The example code should not assume that 'char' is signed --
 not all compilers implement char as default-signed. I suggest changing the
 above functions to use 'signed char' if you're trying to represent
 negative char in a portable manner.

 unsigned-by-default
