Could you paste in the code that you're using?  Or what specifically those 4-8 
bytes are?  I suspect it's either the wrong byte vector being used or that 
you're returning a pointer to a temporary value -- i.e.:

cont char *foo()
{
  ByteVector f("foo");
  return f.data();
}

The above won't work because when f goes out of scope it takes its allocated 
memory with it.  :-)
