bug#15583: 24.3.50; GC crashes

[Richard Stallman]

Over the past few weeks, since updating, I have had several crashes in
mark_object.  The crashes started when I updated somewhere between Sep
17 and Sep 22.  (I don't know how to tell more precisely when that
was.)

I did another update a week ago, hoping the problem would go away,
but yesterday I got another crash of the same sort.

My previous update had been around Aug 18; the crashes did not
happen in that version.

mark_object is reached about 3 levels down from mark_memory.
Thus, I could not easily tell much about what data structure it was.
If it is useful, I will try harder to get more info.
