First, please check if this equivalent and simpler recipe also
reproduces the problem, to make sure this is the same bug:

  emacs --batch -q --eval "(apply 'string (make-list 1122176 ?a)))"

If so, please recompile without optimizations:

  CFLAGS="-g" ./configure
  make

and see if you can obtain a cleaner backtrace.
