Bug description: Segmentation fault in mysqli_stmt_execute
Description:
------------
I'have not yet isolated the problem, but since updating to 5.3.0
(snapshot), some prepared statement cause segmentation fault.
Reproduce code:
---------------
NOTE : Fields 0 to 4 are php serialized objects.
$update_stmt->bind_param('bbbbbs', $bidon, $bidon, $bidon, $bidon,
$bidon,$system_name);
$update_stmt->send_long_data(0,
$serializedFieldRef);
$update_stmt->send_long_data(1,
$serializedFieldRef2);
$update_stmt->send_long_data(2,
$serializedFieldRef3);
$update_stmt->send_long_data(3,
$serializedFieldRef4);
$update_stmt->send_long_data(4,
$serializedSelection); $update_stmt->execute();
Expected result:
----------------
The query is executed
Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
