# bug#1644: Insertion of more than 3 NULL columns with parameter binding fails

# Using prepared statements, insertion of more than three columns with NULL
# values fails to insert additional NULLS.  After the third column NULLS will
# be inserted into the database as zeros.
# First insert four columns of a value (i.e. 22) to verify binding is working
# correctly.  Then Bind to each columns bind parameter an is_null value of 1.
# Then insert four more columns of integers, just for sanity.
# A subsequent select on the server will result in this:
# mysql> select * from foo_dfr;
# +------+------+------+------+
# | col1 | col2 | col3 | col4 |
# +------+------+------+------+
# |   22 |   22 |   22 |   22 |
# | NULL | NULL | NULL |    0 |
# |   88 |   88 |   88 |   88 |
# +------+------+------+------+

# Test is extended to more columns - code stores bit vector in bytes.
