Re: Fix to long-standing crashes in GC

[Richard Stallman]

    But that's already checked:
    mark_memory calls makr_maybe_object and makr_maybe_pointer, but of which
    check for every object whether it's currently live (which really means
    "allocated" in the sense that it hasn't been reclaimed by the GC yet).
    That's what live_consp_, live_stringp_p, ... are for.

I had not noticed the function mark_maybe_object when I wrote
my previous message.  Now I am as puzzled as you are by this
failure.
