#45931 [NEW]: session_start causes "The XML source file is unavailable for viewing" on IE.

From: 2simpletest at gmail dot com Operating system: Windows Server 2003 Enterprise PHP version: 5.2.6 PHP Bug Type: Session related Bug description: session_start causes "The XML source file is unavailable for viewing" on IE. Description: ------------ Have tried this in IE6 and IE7 - same problem happens, but doesn't happen in Firefox. Basically, the script won't let you view source on a dynamically generated XML document if the script starts a session. This in itself is not so bad, but it also makes Flex think it hasn't loaded a proper XML document, which is a much bigger problem for us. The only thing different with this build of PHP from the default is the inclusion of the MySQL and GD2 libraries, we have added a path for the log, and the magic_quotes directive has been modified back and forth. Hope this helps, Reproduce code: --------------- <?php session_start(); //comment this line out and it works. echo "<?xml version=\"1.0\" encoding=\"ISO-8859-1\" ?>\n"; echo "<root>\n"; echo "\t<item>value</item>\n"; echo "</root>"; ?> Expected result: ---------------- You should see a short XML document displayed (which you will), but when you right click and view source it should let you actually see the source code (which it won't). Actual result: -------------- instead of showing source it prompts with a messagebox reading "The XML source file is unavailable for viewing". The source is not displayed. -- Edit bug report at http://bugs.php.net/?id=45931&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45931&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45931&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45931&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45931&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45931&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45931&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45931&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45931&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45931&r=support Expected behavior: http://bugs.php.net/fix.php?id=45931&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45931&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45931&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45931&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45931&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45931&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45931&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45931&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45931&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45931&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45931&r=mysqlcfg
