Description:
------------
ODBC crashes when using php script included (using a MySQL database), and an

ALERT - canary mismatch on efree() - heap overflow detected (attacker 'X.X.X.X', etc ...)

line pops up in the error.log for apache.

This happens on current stable Debian 5.0 "lenny" AMD64, with system up to date as of today, running: apache2, php5, mysql-server.

Compiling latest MySQL odbc driver version 5.1.5 doesn't crash, but does lock up the calling process if same script is run with php5 client from command line.


Reproduce code:
---------------
$conn="DRIVER={MySQL}; DatabaseName='test'; CommLinks=tcpip(Host=localhost); ";
$conn=odbc_connect($conn, "user", "");
$sql='SELECT * FROM test.T1;';
echo $sql;
$pg_query=odbc_exec($pg_conn, $sql);
odbc_close($pg_conn);
echo "A";

I did two clean installs of Debian 5.0 AMD64 to check I didn't have anything wrong installed.
