ID: 27408 User updated by: gregor_macdougall at yahoo dot com Reported By: gregor_macdougall at yahoo dot com -Status: Feedback +Status: Open Bug Type: XMLRPC-EPI related Operating System: Linux PHP Version: 4CVS-2004-02-27 New Comment: I can confirm that this bug does occur, and only occurs on our x86_64 systems. Here is a log of me running the test code on the latest php5 snapshot (same thing occurs with php4 stable). php5 was built with "./configure --with-xmlrpc". Script started on Mon Mar 8 10:18:14 2004 gregor@ariel:~ $ cat test.php <?php $response = '<?xml version="1.0"?> <methodResponse><params><param> <value><string>Test</string></value> </param></params></methodResponse>'; print xmlrpc_decode($response . "\n"); ?> gregor@ariel:~ $ uname -sm Linux i686 gregor@ariel:~r $ php5-200403081630/sapi/cli/php test.php Test gregor@ariel:~ $ ssh io gregor@io:~ $ uname -sm Linux x86_64 gregor@io:~ $ php5-200403081630/sapi/cli/php test.php Segmentation fault gregor@io:~ $ logout gregor@ariel:~ $ ssh hyperion gregor@hyperion $ uname -sm Linux x86_64 gregor@hyperion $ php5-200403081630/sapi/cli/php test.php Segmentation fault gregor@hyperion $ logout gregor@ariel:~ $ ssh pandora gregor@pandora:~> uname -sm Linux x86_64 gregor@pandora:~> php5-200403081630/sapi/cli/php test.php Segmentation fault gregor@pandora:~> logout Script done on Mon Mar 8 10:20:19 2004 ariel is my local x86 box, io, hyperion, and pandora are our 3 opteron servers. The code runs successfully on the x86 box, and segfaults on all 3 opterons.

Leave bug as feedback until you or another user of a 64 bit system can confirm that the bug exists or if it is fixed. ------------------------------------------------------------------------ [2004-03-08 02:43:38] gregor_macdougall at yahoo dot com You need to make sure that the XML contained in the $response variable is properly formed XML. The interface for bugs.php.net caused a new line character to be placed in the midst of the </param> tag, which is not valid and causes the XML parse error you received. You can fix this by removing the new line in the </param> tag, and moving it to before the tag. Sorry for any confusion caused by this. ------------------------------------------------------------------------ [2004-03-07 22:52:47] iliaa@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip I've tried running the given example using PHP 5 & 4 and got an identical response which looks like this: xpat reports error code 4 description: not well-formed (invalid token) line: 3 column: 0 byte index: 95 total bytes: 0 data beginning 10 before byte index: lue></par am></params></methodResponse> ------------------------------------------------------------------------ [2004-02-27 11:20:55] gregor_macdougall at yahoo dot com A segfault also occurs with the most recent php5 cvs cnapshot. If you would like the backtrace information for php5 as well, please let me know. ------------------------------------------------------------------------ [2004-02-27 02:54:22] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php5-latest.tar.gz For Windows: http://snaps.php.net/win32/php5-win32-latest.zip There are some changes in HEAD, so please try it out. (we can then merge those into the stable branch if they make any difference..) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
