Looking at oci_handle_closer() breifly, then the first thing that catches my eye is we don't check H->err because we attempt to free the handle.

I'm not on a dev machine, so I can't write a patch. Could you try and see if something along these lines will work for you:

1) Open /src/ext/pdo_oci/oci_driver.c and find line 215 (trunk, might be the same in 5.x)
2) Wrap line 215 and 216 inside an if conditional like so:

if (H->err) {
	OCIHandleFree(H->err, OCI_HTYPE_ERROR);
	H->err = NULL;
}

As an additional info, i changed to using the OCI 11.1 Instaclient Library to compile against with the same error as described in the original report.

When applying the patch this sort of breaks it completly for both my other bug http://bugs.php.net/bug.php?id=52957 and this a comparable error :-)

I get a binary output of a screen and this error:

Errors in file :
OCI-21500: internal error code, arguments: [kghfrempty:ds], [0xC84EB3C], [], [], [], [], [], []

GDB has the following backtraces:

When developing Drupal 7.x pdo_oci driver (https://github.com/hswong3i/oci) I face this bug too.

Once review with latest patch + cleanup + combo patch with https://bugs.php.net/patch-display.php?bug_id=57702&patch=57702-PHP-5.4-20120623.patch&revision=latest, the segfault no longer exists on 5.4.5-dev (20120623) + Ubuntu 12.04.

may someone apply this patch and get it fixed?
