Oh, it's probably the smart pointer in Ipopt::IpoptApplication to the NLP trying to delete the model.  Reference counting meets the Lua GC!  Is there any way I can tell the RC to leave it alone?  (ie, a cheap way to bump the reference count?)

Me again, sorry.  Yes, AddRef and ReleaseRef worked.  Since AddRef and ReleaseRef don't actually use any features of Referencer (and they ignore the argument if you're not building in debug mode), why not just make the referencer argument a void*?

This means that Rima now (just by the skin of its teeth) supports Ipopt.  It'll take me a while to check this all in tidily though.
