Comment (by hajokirchhoff <mailinglists@…>):

 My guess is that is further complicated by the fact that
 boost/uuid/detail/config.hpp defined BOOST_UUID_USE_SSE2 for Visual Studio
 and emits SSE2 opcodes which the compiler then optimizes. At least if I
 compile the debug version I see an entirely different output for
 _mm_loadu_si128 than with release.
