Thanks, but this bug hasn't been fixed.

Consider the following code (more or less taken from the manuals):

Handle(XCAFApp_Application) App(XCAFApp_Application::GetApplication());
Handle(TDocStd_Document) Doc;
App->NewDocument("MDTV-XCAF",Doc);
STEPCAFControl_Reader reader;
if (reader.ReadFile(FileName)!=IFSelect_RetDone) throw
  std::runtime_error("OpenCASCADE STEP reading failed");
if (!reader.Transfer(Doc)) throw std::runtime_error("OpenCASCADE transfer failed");

6.9.0 would crash on "reader.ReadFile"; 6.9.1 will go on, but still crash on "reader.Trasnfer(Doc)".
There are still several null pointer checks needed.
