In the following code, you'd expect it to print 365. However, it prints a random number instead. The issue is that 'value' is referred to by 'foo', which is referred to by 'foo2'. DMD fails to detect this chain, so 'value' is allocated on the stack, not the heap. Once the function 'clbug' returns, 'value' is popped from the stack and so it ends up printing a random number.

value -> foo -> foo2

void main(){
    clbug()();
}

int delegate() clbug(){
    int value = 365;
    int foo(){
        writeln(value);
        return value;
    }
    int foo2(){
        return foo();
    }
    return &foo2;
}
