Just to make sure there was no problem, i've tried to valgrind the command line program on a simple script using pdo. There are a few memory errors (this can make crashes occur). Note that the leaks are due to the kernel 2.4 threads (so, ignore them). Reproduce code: --------------- <?php $dbh = new PDO('mysql:host=host;dbname=db', 'user', 'pass', array(PDO::ATTR_PERSISTENT => true)); ?> Expected result: ---------------- No memory errors Actual result: -------------- Valgrind's output > valgrind -q --leak-check=full --show-reachable=yes /usr/local/src/php-5.2.5/sapi/cli/php test_pdo.php ==10313== Invalid read of size 4 ==10313== at
