Yep. I've got a similar result here.

To reproduce you only need one row in the table:

---snip---

create table in_crash (

  a    int  primary key,
  b    int,
  c    int,
  d    int,
  e    int,
  f    int,
  g    int,
  h    int,
  i    int,
  j    int,
  k    int,
  l    int,
  m    int,
  n    int,
  o    int,
  p    int,
  q    int,
  r    int,
  s    int,
  t    int,
  u    int,
  v    int,
  w    int,
  x    int,
  y    int,
  z    int,
  a1   int,
  a2   int,
  a3   int,
  a4   int,
  a5   int,
  a6   int,
  a7   int,
  a8   int,
  a9   int,
  b1   int,
  b2   int,
  b3   int,
  b4   int,
  b5   int,
  b6   int

) type = Innobase;

insert into in_crash values
(1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1);

explain select * from in_crash where a > 0 and a < 50;

*boom*
