Bug #14975	Memory Leak with odbc driver using PHP
Submitted:	16 Nov 2005 11:05	Modified:	29 Sep 2008 16:22
Reporter:	Manel Caro	Email Updates:
Status:	Won't fix	Impact on me:	None
Category:	MaxDB	Severity:	S1 (Critical)
Version:	7.5.00.23 and 7.6.00.12	OS:	Windows (Windows 2003 Server and XP Prof.)
Assigned to:	Ulf Wendel	CPU Architecture:	Any

Description:
We have a memory leak using Apache 2.0.54 and php 4.4.1 with odbc_connect
and odbc_close functions. The memory leak is about 150 KB using only this
two functions. We use odbc for connect to MAXDB database version
7.6.00.12. It produce a crash of Apache when it have about 100 MB.

I use a odbc driver 7.6.00.00

I think is possible that bug are in odbc driver, maybe ... ??

Thanks.
Manel.

Reproduce code:
---------------
<?php

$cID= odbc_connect("DSN", "USER", "PASS");
----
more code here {we try without the code and only with this functions and
the result is the same }
----
if($cID){
 odbc_close($cID);
}

?>

How to repeat:
Executing this code:

<?php

$cID= odbc_connect("DSN", "USER", "PASS");
----
more code here {we try without the code and only with this functions and
the result is the same }
----
if($cID){
 odbc_close($cID);
}

?>
