Being pragmatic, I call that a _philosophical_ objection rather than a
bug because the code does actually work in practice as far as I can
tell. But you can call it a bug if you like. If you want me to give in
and call it a bug, then you will have to come up with an actual case
where the code fails to do the right thing - memory use after free,
double free, memory leak, oops, etc.
