[Boost-users] using boost shared memory

I'm contemplating using boost to implement inter process communication between a 32 bit process and a 64 bit process. I'm pretty sure there will be no problem at the raw bits level, but I suspect that if I attempt to use any of the higher order constructs, such as allocators or message queues, the disparate size of pointers will make hash of it. Does anyone have any experience (or advice) ?
