OK, so GCPROs won't help.

Yes, very much so.  You need to `staticpro' them.

Well, Lisp_Objects in the stack are protected by stack scanning or GCPRO,
Lisp_Objects in the static area are protected by staticpro, and Lisp_Objects
in the heap are protected by tracing, so you should make sure that any
Lisp_Objects in the heap are properly traced (typically, that means that
they are properly handled by mark_object).
