Apparently amd64/FreeBSD cannot run valgrind. I get this when trying
to install it:
===> valgrind-352_7 is only for i386, while you are running amd64.***
Error code 1
Is there anything else that's amd64/FreeBSD friendly I can use?

We have same problem with every sql query we tried:
<?php
$conn = odbc_connect("FreeTDS", "user", "name");
$query = "SELECT * FROM systypes";
$result = odbc_exec($conn,$query);
?>
result:
--------
ALERT - canary mismatch on efree() - heap overflow detected (attacker
'127.0.0.1', file '/var/www/test.php', line 3)

Description:
------------
Getting an "ALERT - canary mismatch on efree() - heap overflow
detected" error when running two certain queries. This seems to be
triggered when the second query runs. The error indicates the
mssql_free_result() is the offender, but it happens even when
mssql_free_result() is omitted (however does not show the offending line
number). This bug is the similar, if not the same, as #40119.
Reproduce code:
---------------

Expected result:
----------------
To run without error and exit cleanly.
Actual result:
--------------
ALERT - canary mismatch on efree() - heap overflow detected (attacker
'REMOTE_ADDR not set', file '/usr/home/bwbuilders/test.php', line 33)
