I thought it might have been ANTINEWS month and I missed it :-)

Maybe.  But the cause of the SEGFAULT must be elsewhere.  I have no
idea how

4. make_list interrupted by QUIT

could happen "while the temporary copy is being created" when
timer_check has set Vinhibit_quit to t.

inhibit_quit inhibits process_quit_flag(), but not process_pending_signals(), if I'm reading this correctly:

#define QUIT                        \
  do {                            \
    if (!NILP (Vquit_flag) && NILP (Vinhibit_quit))    \
      process_quit_flag ();                \
    else if (pending_signals)                \
      process_pending_signals ();            \
  } while (false)

Maybe it should.
