I think I found the problem.  As far as I can tell, XRE_TermEmbedding 
deletes the object I pass as aAppDirProvider to XRE_InitEmbedding so I 
need to make sure I don't delete it myself.  I suppose this depends on 
how I've implemented reference counting and whether I keep an extra 
reference myself.  I'm still wrapping my head around all of that but at 
least I have a way that doesn't crash (or at least doesn't crash in this 
particular way).
