+Subject: [PATCH] hpx: receiver: Remove std::move() call
+
+This fixes the following warning:
+
+|/home/kurt/git/libgeodecomp/src/libgeodecomp/communication/hpxreceiver.h:138:29: warning: moving a local object in a return statement prevents copy elision [-Wpessimizing-move]
+|  138 |         return std::move(vec);
+
+The compiler should be smart enough to optimize the correct way :).
