I’m using it with Informix IDS 10 and php 5.2.5. It works perfectly until I try to fetch a row with a datetime field = null. It generates a SEGFAULT in apache. If the datetime field has any value, it works perfectly. But with a null value it crash. I also try with iODBC and the result was the same. Thanks and Regards Emiliano S. Romero Reproduce code: --------------- $r = $pdo->query("select id,date from table"); while($a = $r->fetch()) { var_dump($a); // it'll echo until a null value in date } Expected result: ---------------- Fetched Data Actual result: -------------- Core was generated by `/usr/sbin/apache2-php5 -D PHP5 -D DEFAULT_VHOST -D INFO -d /usr/lib64/apache2-p'.
