Instantiating a PDO object from a PHP script that is called from the CLI results in a seg fault. Running the same script from a browser is perfectly ok. I am using PDO + PDO_OCI in a large web app with no problems, but when I coded up some PDO/OCI code to run within a cronjob, this happens.

Reproduce code:

try {
        $dbh = new PDO("oci:dbname=<host>", "<user>", "<pass>");
}catch(PDOException $e) {
        die("Error: " . $e->getMessage() );
$dbh = null;

echo "I am never reached";


Expected result:
From the browser I see: "I am never reached".
From the CLI: immediate seg fault.

After more poking around I have determined that this is only a problem when a PDO object with driver type of Oracle is used. Trying to create an empty PDO objects results in missing parameters (good!) but once the "oci:dbname=<db>" argument is thrown in, the seg fault appears. We are re-compiling with debugging enabled, so hopefully soon I can provide more info.

This had to do with how the oci8 library was compiled in. Previously we were doing:


but removing the "shared" attribute and having just:


thereby defaulting to "static" works. No more segfaults. Since the PDO modules had to be compiled in as shared we figured the same was true for OCI8. Not the case.
