PHP 7RC5 
Centos 6.7
Oracle Instaclient 12.1 (from rpm) 
Apache/2.2.15

If you uncomment the oci_free_results() in the code below apache will segfault. If you only call oci_free_results() once, it does not.

Test script:
---------------
<?php
$SETTINGS_DB_username		=	"xxxxx";
$SETTINGS_DB_password		=	"xxxxx";
$SETTINGS_DB_ip			=	"10.10.10.202/XX";

// Connection String
if (!isset ($dbConx)) {
	$dbConx = oci_pconnect ( "$SETTINGS_DB_username", "$SETTINGS_DB_password", "$SETTINGS_DB_ip" );
}

function ORACLE_GET_MONTH()
{
	$SQL="SELECT TRUNC(SYSDATE, 'MONTH') AS MONTH FROM DUAL";
	$stmt = oci_parse ( $GLOBALS ['dbConx'], $SQL );
	oci_execute ( $stmt, OCI_DEFAULT );
	$result = oci_fetch_assoc ( $stmt );
	return $result['MONTH'];
	//oci_free_statement ( $stmt );
}

function ORACLE_GET_YEAR()
{
	$SQL="SELECT TRUNC(SYSDATE, 'YEAR') AS YEAR FROM DUAL";
	$stmt = oci_parse ( $GLOBALS ['dbConx'], $SQL );
	oci_execute ( $stmt, OCI_DEFAULT );
	$result = oci_fetch_assoc ( $stmt );
	return $result['YEAR'];
	//oci_free_statement ( $stmt );
}

$oci_month=ORACLE_GET_MONTH();
$oci_year=ORACLE_GET_YEAR();

echo "Month: $oci_month<br />";
echo "Year: $oci_year<br />";
