New Comment:
Good too hear that it does not happen with mysqlnd.
It is hard to comment without a reproducible test case.
If you cannot isolate the issue, maybe you can check if the problem
exists with the latest version of the MySQL Client Library and maybe you
can even use a debug version?
Thanks

I'have compiled php with mysqlnd (--with-mysqli=mysqlnd) and the
problem is solved.
Note that with earlyer version of php, 5.2.9, there was no problem with
libmysql and the same query.

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.
