Hi!, I?m have installed PDO_ODBC with unixodbc. 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()) {
  // 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'.
Program terminated with signal 11, Segmentation fault.
