	Sounds (feels) like it aborted somewhere..

	The location isn't very clear; it propably is optimized
	binary, but within its enclosing while(){..} loop.
	If so, possibly that is  realloc()  which blows up.
	It could be that  ssfgets()  function has a off-by-one
	(or some such) bug, and it stomps beyond the end of
	the allocated memory block.

	However I don't see this at SPARC/Solaris 2.6 ...
