Description:
------------
This is an example of code that will cause PHP to segfault
on exit.  It will otherwise perform all functions, the *exit* causes the segfault

The combination appears to be the use of TWO(2) include files coupled with a *persistent* odbc connection Run this, type something for input, that is not a file or hit ctrl-d

Below is segfault2.php:
<?php
function do_nothing() {print "I did nothing\n";}
?>

Does same thing with cgi/sapi && much lighter weight options list, this was a recent re-compile to see if problem still in 4.3.4.  Tested with 4.3.1 cli/cgi also.

Reproduce code:
---------------
<?php
include_once("./segfault2.php");
// db_webdoc.inc.php appropriate php wrappings:
// $dsn = "some_dsn";
// $dbuser = "username";
// $dbpass = "password";
$dbcfg = getcwd() . "/includes/db_webdoc.inc.php";
include_once($dbcfg);
$dbh = odbc_pconnect($dsn, $dbuser, $dbpass);
while($fbase = fgets(STDIN, 1024)) {
        $fbase = trim($fbase);
        clearstatcache();
        if(!is_file($fbase)) {
                print "No such file: $fbase\n";
                break;
        }
}
exit(0);
?>


Expected result:
----------------
Should exit with status 0.

Actual result:
--------------
Exits by segfaulting with status 139
