It looks like when calling the following line (Visual C++)
CoCreateInstance(CLSID_TaskbarList,NULL,CLSCTX_INPROC_SERVER,IID_PPV_ARGS(&pTaskbarList));
with ITaskbarList3* pTaskbarList;

The pointer returned is not null but an int 1 causing an access violation in
the application.
The app (FAR Manager) is open source so I was able to pull out what seems to be
the offending line.
