Over 180 million records that we could not get a number data.

Table
A int(12)
B int(12)
C int(12)
A varchar(100)

I made table that inserted over 180 million(180,096,936) records. And I executed follow SQL language.

select C, A from table order by C, A ASC;
Value C is all "0". However, all C value contained number without 0.
By the way, Over 170 million(170,716,433) record that we can get true value from the table.

I confirmed Aria, MyISAM, InnoDB, The problem was happened. It not seem to relation database format. I guess just bug of the MariaDB.

If you need test data. I send CSV file contain over 180 million lines. Please let me know.
