Reproduced with (dotimes (i 100) (stress-speed-read (current-buffer)))).
Ugh, it seems that we never initialize undo-list of indirect buffer. You can use
this trivial fix just to avoid crash:

name = Fcopy_sequence (name);
set_string_intervals (name, NULL);
bset_name (b, name);
+ bset_undo_list (b, BVAR (b->base_buffer, undo_list));
reset_buffer (b);
reset_buffer_local_variables (b, 1);
But this bug raises an interesting question: should an indirect buffer's undo list
be always the same as the one of its base buffer?
