Description:
------------
It looks like php5 - works fine. Until I try to php5-interbase functions.
# Options for php5-5.2.5
WITH_CLI=true
WITH_CGI=true
WITH_SUHOSIN=true
WITH_MULTIBYTE=true
WITH_FASTCGI=true
WITH_PATHINFO=true

And php5 compiled only with one extension 'php5-interbase'. No other etnension is used.

Firebird-server running on the same mashine and it looks works fine, I can simple connect and make queries from other mashine.
//firebird-client-2.0.3_1 //firebird-server-2.0.3_1

Reproduce code:
---------------
<? $ibdbc = ibase_connect ('localhost:/baza/DB1.GDB', 'SYSDBA', 'masterkey'); 
echo "OK"; 
?>

Expected result:
----------------
I expecting to see.
>'OK'

Actual result:
--------------
But every time I get: 
>'Segementation fault( core dumped )'
or 
>'Segementation fault: 11'

I've solve this problem for me. In fact, I think, problem wath in firebird-client2.0.3.
As a solution, I 've replace `libfbclient.so.2.0.3` (on my FreeBSD/amd64  7.0_beta3) with a precompiled same file from firebird-client-2.0.3.tbz package for FreeBSD/amd64 6.2STABLE . And than rebuild `php5-interbase` and now everything looks fine.
