Previous Comments: ------------------------------------------------------------------------ [2003-05-18 15:00:06] iliaa@php.net Not enough information was provided for us to be able to handle this bug. Please re-read the instructions at http://bugs.php.net/how-to-report.php If you can provide more information, feel free to add it to this bug and change the status back to "Open". Thank you for your interest in PHP. Could you provide the smallest possible php script that could be used to replicate the crash & the output of var_dump($ftp_handle) just before you do ftp_close() on it. ------------------------------------------------------------------------ [2003-05-18 14:43:32] pekka at studio-on-the dot net Oh, and Apache is 1.3.27. ------------------------------------------------------------------------ [2003-05-18 14:42:04] pekka at studio-on-the dot net I have an ftp upload script (non public code), which ends in plain ftp_close($connection); Where $connection is opened handle. After installing RC3 (as module) I a crash: Event viewer: "Faulting application Apache.exe, version 0.0.0.0, faulting module php4ts.dll, version 4.3.2.2, fault address 0x000b9fc4." or "Faulting application Apache.exe, version 0.0.0.0, faulting module ntdll.dll, version 5.1.2600.1106, fault address 0x00002109." FTP is disconneted by the function before crash (ftp logs show session was perfect and complete). I have tried it with local ftp server and remote ones. I tried also with ftp_close(); and got no crash (and of course no disconnect either) If I used ftp_close($fdfdf); where $fdfdf is NOT an opened ftp handle, Apache just hangs page load after output code before ftp_close BUT without a crash. If I comment line /* ftp_close($connection); */ the whole script runs ok, except ftp remains open of course. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23683&edit=1
