It's a beginning.  Thanks.

The next step is to find out what object is the argument passed to
mark_object in frame #1.  This is the object that caused the abort.

Also, please send the output of the GDB command xbacktrace, it should
produce the Lisp traceback at this point (although it looks like Emacs
crashed right at startup, so the Lisp traceback will not tell anything

This is wrong.  etc/DEBUG says:

                                                            The variable
    `last_marked_index' holds the index into the `last_marked' array one
    place beyond where the pointer to the very last marked object is

See that ``one place beyond'' part?  So you should have said

(gdb) print last_marked[21]
