To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes.

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
