Description:
------------
If i build lang/php5-extensions with module interbase then don't work connect firebird.
If build lang/php5 with argument in MakeFile "--with-interbase=/usr/local" then connect it's work.



Test script:
---------------
<?php                                                                            $link=ibase_connect('test:base_test.gdb','user','user','win1251',0,1,'main');    ?>

Actual result:
--------------
In the course of debugging by means of GDB I have pressed Ctrl-C because the program hangs up, can be goes in cycles.
