Zeev, can you take a look.. Previous Comments: ------------------------------------------------------------------------ [2004-01-27 03:33:31] wmeler at wp-sa dot pl Zeev corrected #21513. It won't help. As long as zend_timeout calls longjmp (through zend_error, php_error_cb and zend_bailout) shutdown functions can get memory, locks - any objects in undefined state. 2 years - no change ... ------------------------------------------------------------------------ [2004-01-26 22:20:02] [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 Zeev applied some fix recently, so please test. ------------------------------------------------------------------------ [2003-08-13 21:43:09] [EMAIL PROTECTED] I could finally reproduce this. The patches didn't make any difference. ------------------------------------------------------------------------ [2003-07-21 04:18:51] wmeler at wp-sa dot pl patches work together http://strony.wp.pl/wp/wmeler/ ------------------------------------------------------------------------ [2003-07-21 02:46:15] wmeler at wp-sa dot pl As I said - heap corrupted. backtrace: #0 0x40393966 in _efree (ptr=0x42671030, __zend_filename=0x403e5840 "/tmp/php4-STABLE-200307081130/Zend/zend_execute_API.c", __zend_lineno=291, __zend_orig_filename=0x403e5ca0 "/tmp/php4-STABLE-200307081130/Zend/zend_variables.c", __zend_orig_lineno=44) at /tmp/php4-STABLE-200307081130/Zend/zend_alloc.c:259 #1 0x403a3e18 in _zval_dtor (zvalue=0x81d6018, __zend_filename=0x403e5840 "/tmp/php4-STABLE-200307081130/Zend/zend_execute_API.c", __zend_lineno=291) at /tmp/php4-STABLE-200307081130/Zend/zend_variables.c:61 #2 0x4039b878 in _zval_ptr_dtor (zval_ptr=0x81d60d4, __zend_filename=0x403e5ca0 "/tmp/php4-STABLE-200307081130/Zend/zend_variables.c", __zend_lineno=167) at /tmp/php4-STABLE-200307081130/Zend/zend_execute_API.c:291 #3 0x403a40d2 in _zval_ptr_dtor_wrapper (zval_ptr=0x81d60d4) at /tmp/php4-STABLE-200307081130/Zend/zend_variables.c:167 #4 0x403aa7a3 in zend_hash_destroy (ht=0x81bfa94) at /tmp/php4-STABLE-200307081130/Zend/zend_hash.c:543 #5 0x4039b361 in shutdown_executor (tsrm_ls=0x81aa7f0) at /tmp/php4-STABLE-200307081130/Zend/zend_execute_API.c:186 #6 0x403a546d in zend_deactivate (tsrm_ls=0x81aa7f0) at /tmp/php4-STABLE-200307081130/Zend/zend.c:666 #7 0x40374772 in php_request_shutdown (dummy=0x0) at /tmp/php4-STABLE-200307081130/main/main.c:995 #8 0x403c4923 in php_apache_request_dtor (r=0x81a6830, tsrm_ls=0x81aa7f0) at /tmp/php4-STABLE-200307081130/sapi/apache2handler/sapi_apache2.c:445 #9 0x403c4c4d in php_handler (r=0x81a6830) at /tmp/php4-STABLE-200307081130/sapi/apache2handler/sapi_apache2.c:541 #10 0x808269e in ap_run_handler (r=0x81a6830) at config.c:194 With my patch there are almost no problems. The problem is that shutdown function won't execute - EG(timeout) flag should be cleared before execution of shutdown function. I can correct it if you want. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
