I can confirm this bug! Appears under Debian Linux too.

One curious example:

a simple php-script that reads all records of a db-table and echo's them works fine with e.g. table a,b and c. when I trie it with e.g. table d and e, PHP crashes with a segmentation fault in the apache-error-log.

I used the following script:

###########################################################
<html>
<head>
<title>PHP/InterBase test</title>
</head>
<body>
<?
$conn=ibase_pconnect ("localhost:/path/to/db-file.gdb", "user", "password");
   if (!$conn) 
   {
    	echo "Acess Denied!<br>";
        exit;
   }

   $result=ibase_query($conn, "select * from any_table");
   if (!$result)
   {
   	echo "<br>Error executing query select count!";
    	exit;
   }

    while ($row=ibase_fetch_row ($result)) {
    	echo $row[0] . "<br>";
    }

    ibase_close($conn);
?>
</body>
</html>



It happens only with ibase_connect after the execution of the following ibase-function. ibase_pconnect seems to work fine.

If more info is needed, feel free to contact me via email.

here some more info:

tried the above described situation with PHP 4.0.6 -> works fine. 

will now have a look at php-source changes in the interbase modul between version PHP 4.0.6 and PHP 4.1.1...

does not seem to be a problem with the interbase-module code, compiling and using PHP 4.1.1 with interbase-module-code of PHP 4.0.6 results in the same error described above!

finally tried it with PHP 4.2.0-dev fresh out of CVS, but did not help. ibase_connect crashes PHP with seg.fault - not always, but quite often.

Should be fixed in today CVS (4.3.0-dev)

same as bug #1549 - #15992

you'll find an example about how to use ibase_close() at:
