Martin will probably tell, but in any case I don't think this is
related to the abort we are discussing.

We are looking for Lisp code that would show calls to some primitives,
wherein we could look for potential bugs on the C level.  Does the
body of Lisp code inside save-excursion in the first occurrence call
any primitives, or any functions at all?  If so, can you show that
body?
