./mtr --mysqld=--default-storage-engine=maria main.subselect3_jcl6

shows in the diff:

 select t21.* from t21,t22 where t21.a = t22.a and
 t22.a in (select t12.a from t11, t12 where t11.a in(255,256) and t11.a = t12.a and t11.c is null) and t22.c is null order by t21.a;
 a      b       c
 256    67      NULL
-256    67      NULL

Before the revision above was pushed, the two rows were missing.
