Re: [Boost-users] Assigning smart/shared_ptr pointer to C struct

struct S *s = (struct S *)malloc(sizeof(struct S));

s->aptr is uninitialized here because you haven't invoked the constructor of S yet. s now points to raw bytes, not to an object of type S. Use new( s ) S; to construct an object in this storage, or better yet, just use S * s = new S;

s->aptr = aptr; return s; }
