      Description

      The part with the wrong result is also reproducible on MySQL and filed as http://bugs.mysql.com/bug.php?id=67345.

      If a server is started with the init-file parameter and the file contains long enough lines (for me, the problem starts with 20,000 characters), it looks like the file stops being executed after such a line is encountered. On a debug build, it causes the assertion failure:

      The attached file contains 3 lines.
      1) creation of a table with one VARCHAR(100) field;
      2) big INSERT (191 values);
      3) small INSERT (1 value).

      For a debug build, the test can be anything, e.g. you can run it as

      perl mysql-test-run.pl --mysqld=--init-file=<path to the attached file> main.1st

      The assertion fails while the init file is executed.

      For a non-debug build, the test is one line:

      SELECT COUNT(*) FROM t1;

      On 5.5, it returns 192, as expected. On 10.0, it returns 0.
