about order of evaluation using shared pointers

I have a doubt about the order of evaluation in a if-clause when using shared pointers.

Suppose I have the following

  struct MyClass {
     bool canUse(){ return false; } // dummmy value
  }

  std::shared_ptr<MyClass> myclass_ptr_;

  /// other code..

  if(myclass_ptr_ && myclass_ptr_->canUse()) {
     // do something
  }

Do you know if in that case C++ always guarantees that myclass_ptr_ is evaluated before myclass_ptr_->canUse() ?

If it is not always the case and myclass_ptr_ might come after for some reason and it is not initialised I am risking to surely crash the app.

When I run this app it seems working fine, but I just want to confirm with someone to avoid nasty surprises in a release.
