ID: 16360 Updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Analyzed Bug Type: Scripting Engine problem Operating System: Linux, Windows PHP Version: 4.0CVS-2002-03-3 New Comment:
When you report error. Disable Zend Optimizer _ALWAYS_. We don't support ZendOptimizer and it's waste of time for both of us. Zend optimizer probably does not work with the patch. To locate line, use die(). Previous Comments: ------------------------------------------------------------------------ [2002-03-31 21:44:32] [EMAIL PROTECTED] Please give me a hint how to locate the line, for I don't know :-) I'm using the Zend Optimizer in addition, nothing else. ------------------------------------------------------------------------ [2002-03-31 20:56:36] [EMAIL PROTECTED] wolfram, Could you locate which line is causing following error? "Unsupported operand types in Unknown on line 0" I don't get this error message with my applicatins. Are you using any cache products? ------------------------------------------------------------------------ [2002-03-31 12:42:45] [EMAIL PROTECTED] After applying the patch above, my Apache segfaults on scripts which ran fine before or just prints "Unsupported operand types in Unknown on line 0". Using PHP 4.2.0RC1. ------------------------------------------------------------------------ [2002-03-31 12:21:32] [EMAIL PROTECTED] Increasing the refcount width from short to long doesn't solve the issue. A strict upper limit test is badly needed to check whether the refcounter can be increased in the given limit or not. I suggest to throw a memory exhausted error with a hint that no more reference counters could be allocated. ------------------------------------------------------------------------ [2002-03-31 05:06:08] [EMAIL PROTECTED] This should be refcount issue. Change _zval_struct's refcount data type from unsingned short to unsinged int, then PHP should be fine upto 4G. Without patch refcount can be upto 64K and no error check is done -> segfualts. ZE2 is changed to use unsinged int already. IIRC.
