Bug Description

It seems that myinsane crashes when trying to validate dates on large tables:

./myinsane -u percona_root -pxxxxxx -d xxxx -t xxxx_stats -c 130790448
-s
Segmentation fault

select count(*) from xxxx_stats;
+-----------+
| count(*) |
+-----------+
| 128357598 |
+-----------+
1 row in set (6 min 56.13 sec)

this works:

./myinsane -u percona_root -pxxxxxxx -d xxxx -t xxxx_stats -c 130790448

This not it seems:

./myinsane -u percona_root -pxxxxxxx -d xxxx -t xxxx_stats -s
Killed

It seems the resultset it too heavy for this server ?

This change the way myinsanechecks the date ,this returns a smaller resultset.

Also this patch add a new parameter to my insabe (-r ) to define the difference between expected and actual number of rows in % when using -c
