Hi to all, Thanks to Dylan Passmore I've fixed a bug in Shmem that provoked unnecessary memory allocation when constructing big objects (twice than necessary, in the extreme case when using boost::array). I've uploaded a easy fix but this sadly breaks ABI. So if you start using Shmem from the CVS, please delete all your Shmem files (if you are using memory mapped files) and be sure to use the same Shmem version in your projects. This change will be officially announced for Shmem 0.94 (I had no intention to do that, but there are some fixes in the CVS and maybe I should release it). I'm working on Interprocess, adding move-semantics to containers (mainly done) and in order to achieve a no-throw move constructor in those containers, I embedding end-nodes of node containers in the container itself (almost done). I plan to release a new snapshot in two weeks, after doing some more fixes and documentation. This new Interprocess snapshot will also break ABI and will add the Dylan's bug-fix to the cocktail. Regards, Ion
