Dear Ion and Boost.Interprocessors, I'm very interested in the status of support for using shared memory across processes of mixed bitnesses particularly on Windows. I see from the thread here: http://lists.boost.org/Archives/boost/2011/02/177696.php and the trac here https://svn.boost.org/trac/boost/ticket/5230 that this has been looked at before. The ticket is marked as fixed in 1.47, but I believe the changes are actually only on trunk at the moment? I appreciate Ion saying in that Trac ticket that support is experimental and requires feedback from real-world users. I'd be happy to be such a guinea pig user. But to help me along the way, I have a couple of queries: - with trunk, what features from Boost.Interprocess are intended to work across bitness? (I'd plan to build both the 32-bit and 64-bit with the same version of MSVC). For instance, might interprocess::managed_shared_memory, interprocess::vector and interprocess::basic_string be expected to work? - Is it possible to back port the changes from trunk to 1.47 or 1.46.1? If so what would I need to copy? AlignedStorage, Move and Interprocess? Many thanks for any help on this, Pete Bartlett
