What is a "vector" for you? Do you mean std::vector? A vector allocated
using malloc()? A vector allocated using new? Just provide a simple piece
of C++ and Python example code that demonstrates the problem and you will
probably get help immediatel.

There are things like that, but without context it's pretty hard to tell
what's going on.
