Mail from god

Just came across an old mail from God aka Bjarne Stroustrup. I was ecstatic when I received a mail from him as I never expected a reply for such a naive query. Below is the mail

Don't delete a pointer twice.

I don't see any alternative to tracking down that bug. It is serious and
could easily be the indicator of some serious problems with resource
management. Try using a leak detector; sometimes they can catch double
deletions.
