Description:
------------
When inserting a -1 into a TIMESTAMP field in an interbase 7 database Apache crashes. When looking at the "More info" in the WinXP crash dialog it shows that it was mod "php_interbase.dll" that caused the crash.

System setup:
 Windows XP Pro, SP2
 Apache/2.0.50 (Win32) (Win32 bin files downloaded)
 PHP/5.0.2, extension INTERBASE used in php.ini
 Interbase 7 (WI-V7.1.0.131), TCP/IP connection (Localhost)
 No Zend optimizer

Note:
 If a value of 0 (zero) is given in the statement, then all works as expected.

Reproduce code:
---------------
1) Create the table "testtable" in a database with one field named "DTField" of type TIMESTAMP.

2) Execute the following code:
   // Crash Code
   $db = ibase_connect('','','','None',0,3);
   $sql = "INSERT INTO TestTable (DTField) VALUES (?)";
   $sth = ibase_query($db_intra, $sql, -1);
   ibase_commit($db);


Expected result:
----------------
The table should have a new entry

Actual result:
--------------
Apache crashes (php_interbase.dll)

Did you build php_interbase.dll from source, or did you use the pre-built one from php.net?
 [2005-02-24 09:10 UTC] sandell at slobtrot dot com
The PHP installation was not altered. It's the original PHP 5.0.2 installation (binary only).

Please try if the error can be reproduced with a php_interbase.dll built from source using the ibase.h header file that comes with Interbase 7.1

Compiling stuff is out of scope for me, sorry. The compiling must be done by someone else who knows how to do it.

Please try using this CVS snapshot:

The new Snapshot (downloaded 1.3.2005) still causes Apache to crash.

Tested with:
- Interbase Server v7.1 (WI-V7.1.0.192).
- Apache 2.0.50
- PHP 5.1.0-DEV

This bug is in fact the same as #32143

Look at the first param to ibase_query(). This is *not* the resource returned from ibase_connect().

The empty parameter is then passed as an empty querystring (as it is not a resource, it is treated as a (query)string). This empty querystring crashes IBserver 7 (but not Firebird 2).

A possible bugfix is suggested, and hopefully a bugfix is on it's way (in PHP 5.3).

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
 
Thank you for the report, and for helping us make PHP better.

Fixed in HEAD and PHP_5_3
