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. ------------------------------------------------------------------------ [2006-06-27 18:28:44] ylee at peragrin dot com Description: ------------ When S_SESSION is passed through a function with global $_SESSION, the apache's child processor segfaults. Reproduce code: --------------- <?php session_id("temp"); session_start(); $_SESSION['a'] = 'test'; function my_get_from($list) { global $_SESSION; // removed code related to manipulating $_SESSION using $list. } my_get_from('a', $_SESSION); if (isset($_SESSION)) { print_r($_SESSION); } ?> Expected result: ---------------- An error message would be nice or being able to access both list will be the most desirable solution. This code used work on 4.* releases. Actual result: -------------- [Tue Jun 27 11:14:16 2006] [notice] child pid 15899 exit signal Segmentation fault (11) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37933&edit=1
