No crash with valid XML either. 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. Previous Comments: ------------------------------------------------------------------------ [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] [EMAIL PROTECTED] 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] [EMAIL PROTECTED] 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..) ------------------------------------------------------------------------ [2004-02-26 18:30:42] gregor_macdougall at yahoo dot com Description: ------------ The xmlrpc_decode function causes PHP to segfault on each of our 3 dual opteron servers. These servers are running various versions of linux and all segfault in a similar way. Our 32-bit x86 servers have no problem with the same code. This segfault occurs when running the following program via the command line. Reproduce code: --------------- <?php $response = '<?xml version="1.0"?> <methodResponse><params><param><value><string>Test</string></value></param></params></methodResponse>'; print xmlrpc_decode($response); ?> Expected result: ---------------- The program should print "Test".
