I can't seem to get a handle on what is causing the problem below.
In particular, why should the AddRef in the running mozilla case belong to
nsBinaryInputStream? I have stepped through the debugger and found that
QueryInterface and Release for this same object don't refer back to
nsBinaryInputStream, but to nsServiceManagerImpl as you would expect. How can
this be?
Could someone help me out here? Is it possible I am linking my plugin
incorrectly? I am currently linking it against the xpcom.lib. Is there
something else I need to do?
