But... QTC_CHECK always returns. Why should it have QNORETURN?

The first non-3rd-party issue (findtoolwindow.cpp) is genuine. Thanks.
A patch is on gerrit now.

I already don't understand the second (branchdialog.cpp) m_model is
always non-null, it's created with new and assigned in the constructor
and never changed afterwards.

Why does it say "Called C++ object pointer is null"?
