Description:

Hello,

I am using OCI8 version 1.2.4 and Oracle Instant Client 10.2.0.3 to connect to an Oracle 10g Express database. 

My code works correctly when using oci_connect() or oci_new_connect() however when I try to use oci_pconnect() i get these in the apache error log:

[notice] child pid 17517 exit signal Segmentation fault (11)

I have been trying to solve this problem on an off for a month, different versions of instant client/php/etc..  every time just reverting back to using oci_connect().

A request to the oci_pconnect() php script works correctly the first time it is called after an apache restart. Subsequent requests do not always work, causing seg faults. The behavior seems to be random. 

Sometimes I get another error along with the seg fault:

oci_fetch_array() [function.oci-fetch-array]: ORA-24338: statement handle not executed in /var/www/html/oracle_script.php

I have tried to do a gdb backtrace however I can't seem to make it catch the seg faulted child process, should I be running apache in a different mode in order to do the gdb backtrace?

Reproduce code:
---------------
$conn=oci_pconnect(_DB_USER,_DB_PASS,_DB_HOST,"AL32UTF8");

$sql = 'BEGIN "XXXXXSelect"(:Cursor,:ErrorNumber,:ErrorText); END;';
$stmt = oci_parse($conn, $sql);
$p_cursor = oci_new_cursor($conn);
oci_bind_by_name($stmt, ":Cursor", $p_cursor, -1, OCI_B_CURSOR);
oci_bind_by_name($stmt, ":ErrorNumber", $ErrorNumber, 18, SQLT_LNG);
oci_bind_by_name($stmt, ":ErrorText", $ErrorText, 4000, SQLT_CHR);
oci_execute($stmt);
oci_execute($p_cursor);
$DataArray=array();
while($row = oci_fetch_array($p_cursor, OCI_ASSOC)) {
  $DataArray[$row['XXXXID']][$row['XXXXID']] = $row;
}
oci_free_statement($stmt);
oci_free_statement($p_cursor);


Actual result:
--------------
in Apache error.log:

oci_fetch_array() [function.oci-fetch-array]: ORA-24338: statement handle not executed in /var/www/html/oracle_script.php

[notice] child pid 17517 exit signal Segmentation fault (11)
