#23573 [NEW]: fread with large number kills script

From: fidian at tiny dot net Operating system: Linux 2.4.18-586tsc PHP version: 4.3.2RC1 PHP Bug Type: Reproducible crash Bug description: fread with large number kills script Running this script causes the server to close the connection. When doing a similar operation to delete a record at the end of the file, the server will run the script, delete the record, restart the script, try to delete a non-existant record (I coded an error message) and then works the second time but it thinks it couldn't delete the record. Really weird. I am using the Debian packaged version of PHP. phpinfo() returns this information: Linux cyberhq 2.4.21-pre5 #1 SMP Sat Mar 1 00:30:11 PST 2003 i686 unknown unknown GNU/Linux Apache/1.3.27 (Unix) Debian GNU/Linux PHP/4.2.3 mod_ssl/2.8.14 OpenSSL/0.9.7a Build Date Apr 21 2003 01:48:55 If you need the configure line, just email me. I don't think it is relevant. Here is my script that I used to finally track down the bug. <?PHP // These few lines are for a good hit counter // to see the problem easier. // They don't need to be here to show the problem. // Seed the "hit.txt" file with an initial number $fp = fopen('hit.txt', 'rb'); $Hit = fgets($fp, 1024); fclose($fp); $Hit ++; echo "Hit: $Hit<br>\n"; $fp = fopen('hit.txt', 'wb'); fputs($fp, $Hit); fclose($fp); // The problem. $fp = fopen('php_bug.txt', "w+"); // Uncomment this to kill the process. //fread($fp, 1080648704); echo "Done."; -- Edit bug report at http://bugs.php.net/?id=23573&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=23573&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=23573&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=23573&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=23573&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=23573&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=23573&r=support Expected behavior: http://bugs.php.net/fix.php?id=23573&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=23573&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=23573&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=23573&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=23573&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=23573&r=dst IIS Stability: http://bugs.php.net/fix.php?id=23573&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=23573&r=gnused
