ID: 20658 Comment by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Feedback Bug Type: Reproducible crash Operating System: Linux 2.4.19-pre4 PHP Version: 4CVS-2002-11-26 (stable) New Comment:
Seems to be fixed now, thanks for the help. Previous Comments: ------------------------------------------------------------------------ [2002-11-26 17:02:17] [EMAIL PROTECTED] Yep. I found a bug in error reporting code while investigating array_walk() and fixed it. Now please try the latest one and it will give you a bit more useful information, I suppose. ------------------------------------------------------------------------ [2002-11-26 16:48:36] [EMAIL PROTECTED] The one I tried and quoted in the bug report was less than 2 hours old at the time of the reporting. Has anything changed between then and now? ------------------------------------------------------------------------ [2002-11-26 15:38:46] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php4-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-latest.zip ------------------------------------------------------------------------ [2002-11-26 13:41:48] [EMAIL PROTECTED] I get a segfault after calling array_walk, in this portion of a script: function get_flat($packageid = 0) { if ($packageid == $this->lastflatid) return $this->flat; $this->lastflatid = $packageid; $this->flat = array(); array_walk(&$this->tree[$packageid], array(&$this, "get_flat_callback")); return $this->flat; } function get_flat_callback($val, $key) { if (is_array($val)) { if (is_int($key)) $this->flat[$key] =& $val; array_walk(&$val, array(&$this, "get_flat_callback")); } } The entire script can be viewed here: http://dali.deviantart.com/~chris/themetree.phps For some odd reason, this code is called twice in the page, however the bug only manifests itself the second time the function is called (which was why I added the first three lines of get_flat() as a temporary workaround) however it is completely reproducible. I could also reproduce it in 4.2.2, and it printed an error message to the php error_log: [26-Nov-2002 10:16:31] PHP Warning: Unable to call (null)() - function does not exist in
