     Type:  Bugs                     |     Status:  new
Milestone:  To Be Determined         |  Component:  interprocess
  Version:  Boost 1.54.0             |   Severity:  Problem
 Keywords:                           |
-------------------------------------+--------------------------
 The win_msg_hdr_t, msg_hdr_t, win_mq_hdr_t, mq_hdr_t use
 typedef typename boost::make_unsigned<difference_type>::type
 size_type;

 The sizeof(size_type) is 32 in 32 bit process and 64 in 64 bit process.
 So when a 32 bit process want to communicate with a 64 bit process, the
 sizeof(msg_hdr_t) is not equal, which would cause process crash.
