+# 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.
