 Maybe.=C2=A0 But the cause of the SEGFAULT must be elsewhere.=C2=A0 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 inhibi= ts process_quit_flag(), but not process_pending_signals(), if I'm readi= ng this correctly:

#define QUIT=C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2= =A0 \

Maybe it should.
