pointer to pointer to heap

[slomoman]

I'm not sure about this:

Does this work?

classA::classA(){
  classA1 pa1 = new classA1;
  classA2 pa2 = new classA2(pa1);
}

classA2::classA2(classA1* p){
  m_pa1 = p; //Member-Variable
}

Later, I create a Thread that gets a pointer to m_pa1 and uses this pointer even after pa2 is destroyed.

threadFunctionBla(..){
  classA2* pa2 = //get out of parameter//;
  classA1* pa1 = pa2->m_pa1;
  //do somwthing.
  //classA2 is detroyed now by another Thread
  pa1->doSomething(); //does this work? I get strange results.

i now it's confusing. if anybody sees any errors or wants to show a btter way, i'd be glad.
