The problem can be reproduced in 5.3 with the following modification of the original test case:
create table t1(a int,b tinyint,c tinyint)engine=myisam;
create table t2(a tinyint,b float,c int, d int, e int, f int, key (b), key(c), key(d), key(e), key(f))engine=myisam;
create table t3(a int,b int,c int, d int, e int, f int, key(a), key(b), key(c), key(d), key(e), key(f))engine=myisam;
create view v as select t2.b a, t1.b b, t2.c c, t2.d d, t2.e e, t2.f f from t1,t2 where t1.a=t2.a;
update t3 natural join v set a:=1;
drop view v;
drop table t1,t2,t3;
I'm also experiencing crashes in make_join_statistics. In my case it is happening when query is used in procedure and when the cursor is opened. I'm not sure if it's the exact same bug. The issue occurs only when the procedure is executed the second time.
The issue can be reproduced without any data in the tables. Please see http://pastebin.com/PZU1igsV for the full schema and procedure.

131008 11:00:07 [ERROR] mysqld got signal 11 ;
Server version: 5.5.33a-MariaDB-log
key_buffer_size=67108864
read_buffer_size=104857600

It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 322192329 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
