So in my project I am getting some weird crashes and I am suspecting it being a problem with QDeferred.
When running Clang-Tidy and Clazy analyzer in QtCreator, I am getting some warning with "C++ object pointer is null" message.
I went and tested with test13 and got the same warning message

I also got this one

Is that a normal case? Maybe this us just because clang doesn't work well with QExplicitlySharedDataPointer.
