I think this is because the padding of the leading '0' is done to the wrong side. ie 0x08 becomes 0x80 I'm using VS2013 on Windows 7. As an example: boost::uuids::uuid uuid = { 0x0a, 0xe0, 0x47, 0x50, 0x0a, 0x0a, 0xeb, 0xec, 0xed, 0xee, 0xfc, 0x08, 0x4d, 0xcf, 0xe7, 0xf5 }; \\ stringstream ss;\\ ss << left << uuid;\\ cout << ss.str() << endl;\\ Outputs: a0e04750-a0a0-ebec-edee-fc804dcfe7f5\\ instead of 0ae04750-0a0a-ebec-edee-fc084dcfe7f5 " Bugs closed Boost 1.62.0 uuid Boost 1.57.0 Problem fixed
