#12051: offset_ptr<void , boost::int32_t, boost::uint64_t> is saved incorrectly on

Milestone:  To Be Determined  |  Component:  interprocess
  Version:  Boost 1.61.0      |   Severity:  Problem

------------------------------+--------------------------
 I'm using offset_ptr<void , boost::int32_t, boost::uint64_t> to work with
 one mapped file from x32 and x64 process. Binary representation of
 offset_ptr is supposed to be same for 32 and 64 bit process.

 In attached example I simply create mapped file and it has different
 content on win32 depending on boost library version. It is offset_ptr
 stored differently:

 on x64:\\
 f8ff ffff ffff ffff - for any version

 on win32:\\
 f8ff ffff ffff ffff - boost version < 1.52\\
 f8ff ffff 0000 0000 - boost version >= 1.52 - this is bug\\

 This behavior causes crash if I save data from x32 process and then open
 it from x64 process. Luckily offset_ptr.hpp header from boost 1.51 works
 in 1.60, but it's hardly a solution...

 Can you guys make offset_ptr 32/64 compatible again?

 Thanks,\\
 Eugene
