Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
Works for me with libmysql and mysqlnd. Please provide a stacktrace and
the version of libmysql you are using.

Description:
------------
PHP segfaults when prepared statement that threw an exception is
reexecuted. pdo_mysql, libmysql. Haven't tested with mysqlnd yet.
Test script:
---------------
<?php
$DB = new PDO("mysql:dbname=test;host=localhost", "root", "",
array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_EMULATE_PREPARES => false));
$DB->exec("CREATE TEMPORARY TABLE t(f VARCHAR(1))");
$stmt = $DB->prepare("INSERT INTO t VALUES(:value)");
$value = "aa";
$stmt->bindParam(":value", $value);
try {
$stmt->execute();
} catch (PDOException $e) {}
$stmt->execute();
Expected result:
----------------
Script successfully executed
Actual result:
--------------
Segmentation fault
