It's unclear. Are you *certain* this object was allocated with new?
If that's the case, I can't imagine that the problem is coming from
that particular wrapped function. My advice (as usual) is to reduce
your program to the simplest possible case that still exhibits the
problem. That almost always immediately reveals the problem. I hear
utilities like valgrind can be really useful for situations like this,
too, though I've never used it myself.
