    I hope I haven't been misunderstood. I sure did declare it globally,
    it is so easy - you just put
    it ouside any function. Therefore I am quite sure that the destructor
    doesn't show up because of
    bad scope analyzis. The thiing is that I am really confused that a
    destructor is called which,
    following all the rules of a good sense, should happen only in
    situations when the given object comes out of scope.

    The thing that was actually supposed to happen is that the global
    variables' contents stay
    untouched after the signal handler exits, even if the signal handler
    explicitly modified those
    variables. I was prepared to that, and ready to use volatile or
    something, but than this happened which, as I said and you have
    noticed, certainly should not be allowed to happen.

    I would appreciate at least an answer saying, for an example, "it is
    up to C++" or "It is up to UNICES memory management" or anything, I
    really don't get it.
