So, you are saying the task_with_deps function does *not* copy the dependences and therefore the array has to outlive the function?

----------------
As mentioned before. There is a lot of literal duplication here with no obvious benefit. Use a base class, or other schemes, to cut down on that. Also, the functions further above should share the same code.
