12051	offset_ptr<void , boost::int32_t, boost::uint64_t> is saved incorrectly on win32	anonymous	Ion Gaztañaga	"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,\\
