    var $error;
    var $rowcount;
    var $fields;
    function TDB($h,$u,$p)
        {
            $this->host=$h;
            $this->username=$u;
            $this->password=$p;
            $this->dbh=$this->Connect();
        }
    function Connect()
        {

Segmentation fault doesn't depend on installation type of apache, php and firebird - whenether they are installed from source or package.
Changing OS version package like here: http://bugs.php.net/bug.php?id=43388 does the same result.

I got same problem with FreeBSD 7.0 release + latest ports Apache (or nginx), PHP, Firebird.
Problem is in firebird2-client-2.0.2 port. If you take client version from 6.3 package tree:
ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-6.3-release/databases/firebird-client-2.0.3_1.tbz
then link some missing links in /usr/lib/ then php got work! =)

Now have (all from port tree):
nginx-devel-0.6.29 as webserver, apache will work also, im sure
php5-5.2.5
php5-interbase-5.2.5
firebird-server-2.0.3_1 (or firebird-server-2.0.3_2 tested both)
firebird-client-2.0.3_1 from pakage FreeBSD 6.3 (link above)

So i hope port submiter on FreeBSD will fix soon this problem.
Good luck.

3rd party problem. Not PHP bug -> bogus.
