Hi, Looks like a Boost.Move bug that is causing problems in Interprocess and potentially in other libraries like Container. The bug is present in the soon to be released Boost 1.70. The bug was reported by Nikita Kniazev for Interprocess: https://github.com/boostorg/interprocess/issues/81 I've committed a simple fix in the develop branch: https://github.com/boostorg/move/commit/756c964798ff1110406fab541b85267aefb6... I hope the regression can cycle soon and release managers can approve the patch for Boost 1.70. Best, Ion
