C++ noob here. This reminded me of "Obscure C++ Features" [1] (discussion [2]) - the 'Placement new' feature. Basically, we can allocate memory using malloc and then call the constructor on the allocated memory: // Must allocate our own memory Test *ptr = (Test *)malloc(sizeof(Test)); // Use placement new new (ptr) Test; // Must call the destructor ourselves ptr->~Test(); // Must release the memory ourselves free(ptr); My point is: is possible that the explicit constructor call feature is intended to be used in this use case?
