Description:
------------
Hi, I'm using FreeTDS 0.91.103_2,1 and the this script are running fine in webserver but not in CLI. Maybe PHP are passing invalid pointers to the dbopen() function of FreeTDS. I have several crontab jobs that requires MSSQL connection so I need this bug fixed ASAP.

Ps.: No output in the FreeTDS debug file and the tsql (FreeTDS CLI) are running fine too.

Thanks.

Test script:
---------------
<?php
if (mssql_connect("100.100.100.100", "sa", "thisissparta"))
        print "Connection success\n";
else
        print "Connection error\n";
?>

Actual result:
--------------
(gdb) run test.php

I was able to resolve this by recompiling FreeTDS from source without --enable-sybase-compat.
