Description:
------------
Calling pg_fetch_array() with the results of a division followed by
calling it with a constant causes a segfault. I have confirmed it in
both cgi and mod php 5.0.4 and also in cgi php 5.0.3.
Reproduce code:
---------------
// need a valid database to connect to
// contents don't matter
$query = 'select 1 as one';
$db_user = "your_user";
$db_password = "your_pass";
$db_name = "your_db";
$db_port = 5432;
$connect_string = "user=$db_user " .
"password=$db_password " .
"port=$db_port ".
"dbname=$db_name";
$db_link = pg_connect($connect_string);
$result = pg_exec($db_link, $query);
$i = floor(4/5);
$data = pg_fetch_array($result, $i);
$i = 0;
$data = pg_fetch_array($result, $i);
echo("No segfault");
Expected result:
----------------
No segfault
Actual result:
--------------
gdb backtrace:
