Operating System: WinXP
PHP Version: 5.1.3
New Comment:
I have the same problem. After fix for bug #36934 PHP crashes when
reading BFILES with OCI8.
I receive the same backtrace as crescentfreshpot.
Here is the code to reproduce the bug:
$conn = oci_connect('rtg_owner', 'rtg', $tnsname);
$stmt = oci_parse($conn, "SELECT BFILE FROM IMAGES WHERE IMAGE_ID =
3872");
oci_execute($stmt);
$row = oci_fetch_assoc($stmt);
$img = $row['BFILE'];
var_dump($img);
$img->read(128); // this line causes a crash
echo $img->tell();
I'm using PHP 5CVS-2006-05-08(snap), Apache 2.0.55 and Oracle Instant
Client 10.2.0

Two side notes:
1) Seems to me that any calls to OCI-Lob::xxx() methods in user code
will wipe out oci8 from turning up in the call stack window.
E.g. adjusting reproduce code like:
<code>
oci_execute($stmt);
$lob = oci_fetch_array($stmt,OCI_ASSOC);
var_dump($lob['LOBDATA']->load());
</code>
and no more oci8 in the call stack window
2) Related to bug #37331

That's all that's there.
However, I've adjusted the reproduce code slightly and oci8 does turn
up in the backtrace now:
Reproduce Code
--------------
<?php
$conn = oci_connect('scott', 'tiger', 'xxx')
or die('Cannot connect');
$stmt = oci_parse($conn, "select lobdata from lobtest");
oci_execute($stmt);
$lob = oci_fetch_array($stmt,OCI_ASSOC+OCI_RETURN_LOBS); // crash
var_dump($lob);

And now the kicker: changing OCI_ASSOC to OCI_NUM works fine.

With latest snaps win32 debug pack and 5.1.5-dev this is everything in
the Visual Studio .NET 2003 call stack window when the crash happens.
This is running the reproduce script from the command line. Hope this
helps:
