Description:
I create a table with 500 hash partitions.
I try to select from information_schema.
Crash.

Perhaps the underlying cause is the same as in bug#17129,
but it's a much different symptom, so I report it as a different bug.

How to repeat:
mysql> select count(*) from information_schema.partitions;
+----------+
| count(*) |
+----------+
|       43 |
+----------+
1 row in set (0.03 sec)

mysql> create table txt (s1 int) partition by hash (s1) partitions 500;
Query OK, 0 rows affected (0.28 sec)

mysql> select count(*) from information_schema.partitions;
ERROR 2013 (HY000): Lost connection to MySQL server during query

Thank you for the bug report.
