I can't agree Oliver anymore. I believe some code seems OK does not means you
should write in that way (just think about business flow control using
exception, it's OK, but you should not do so). Now I knew it's OK but I'll
still tell my blog readers it does not recommand to do so. :-)
Thank you all!

Technically it is.

The OS is just kind enough to sweep it under the rug. It won't make it easier
to find "real" leaks with tools, because your developers will tend to say the
same: "It's not a leak, it's cleared by the OS anyway..."

Fix the double-deletes instead - those are real issues! If an object is
double-deleted it might be an indication that it should not have been allocated
on the stack in the first place...
Cheers,
Oliver
