ID: 42420 User updated by: mkwan at darkside dot com dot au Reported By: mkwan at darkside dot com dot au -Status: No Feedback +Status: Open Bug Type: Reproducible crash Operating System: Linux (Fedora 7) -PHP Version: 5.2.3 +PHP Version: 5.2.2 New Comment:
Sorry, but I'm using an RPM installation, and I'm not in a position to compile/install/test/remove a debugging version of PHP just so I can submit a bug report. I don't think a developer would have any trouble reproducing it. One other piece of diagnostic information that may be useful: the following line appears in the Apache log - 127.0.0.1 - - [23/Aug/2007:14:17:43 +1000] "GET ftp://ftp2.bom.gov.au/anon/gen/radar/IDR463.gif HTTP/1.0" 200 22489 "-" "-" So it looks like PHP crashes *after* connecting to the proxy and requesting the file.

To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2007-08-25 02:51:01] mkwan at darkside dot com dot au Description: ------------ Calling the file_get_contents() function with the ftp:// wrapper causes a segmentation fault when an FTP proxy is enabled with the stream_context_get_default function. The machine is running Fedora 7 with an Apache server which has proxying enabled. Just for comparison, the following command DOES work - export ftp_proxy=localhost:8080 wget ftp://ftp2.bom.gov.au/anon/gen/radar/IDR463.gif Reproduce code: --------------- <?php stream_context_get_default ( array ("ftp" => array ("proxy" => "tcp://localhost:8080")) ); $gif = file_get_contents ("ftp://ftp2.bom.gov.au/anon/gen/radar/IDR463.gif";); if ($gif === false) echo "failed\n"; else echo "size = " . strlen ($gif) . "\n"; ?> Expected result: ---------------- I expect to see a message of the form "size = 22544" Actual result: -------------- Segmentation fault ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42420&edit=1
