>Description:
I would think that the following uninitialize
memory would get noticed by g++. I get
no warnings, even when I pass the -Wall
and -Wuninitialized flags.

class no_init {
    private:
    int num;
    char *ptr;

    public:
    no_init(): num(0) {

    }

    ~no_init() {
        delete [] ptr; // This memory is never initialized!
    }
};

int main() {
  no_init();
}

% g++ -static -o noinit -g -Wall -O2 -Wuninitialized no_init.cpp

% ./noinit
Segmentation fault (core dumped)
