Hi,
Compiling recent Qt (5.8 branch) fails due to failing member access in
specialized copy & move constructors
The error is reported like this:
error: ‘ComPtr<B>::InterfaceType* ComPtr<B>::ptr_’ is protected within this
context
ComPtr(ComPtr<U>&& other) throw() : ptr_(other.ptr_) {
Luckily, these are easily fixed by using available accessor functions. Below is
the proposed patch:

functions
