I ran into a problem using multi-array. Not really a "bug", but a bit of unexpected behavior. Most containers have constructors like: template<typename old_t> Container (old_t const&); Allows constructing the new container from any sequence - the new container will have a copy of the contents of the old (usually). If you try this with multi-array you will not get a compilation error, but also will not get anything like what you expected.
