This is version 4.2.3, as this is from our production site (late at night I'll try and do the same for a full debug version of 4.3RC2): Program received signal SIGSEGV, Segmentation fault. 0x080a9b2c in sapi_apache_header_handler () (gdb) bt #0 0x080a9b2c in sapi_apache_header_handler () #1 0x080af403 in sapi_add_header_ex () #2 0x080b5700 in zif_ob_gzhandler () #3 0x08124392 in call_user_function_ex () #4 0x080b20f9 in php_end_ob_buffer () #5 0x080b23bb in php_end_ob_buffers () #6 0x080ac0a7 in php_request_shutdown () #7 0x081530d8 in run_cleanups () #8 0x08151ec8 in ap_clear_pool () #9 0x08151f28 in ap_destroy_pool () #10 0x08151e9b in ap_clear_pool () #11 0x0815e92b in child_main () #12 0x0815ef0b in make_child () #13 0x0815f1e9 in perform_idle_server_maintenance () #14 0x0815f69a in standalone_main () #15 0x0815fc2c in main () Previous Comments: ------------------------------------------------------------------------ [2002-12-04 17:59:13] sniper@php.net status -> open, updated version. (please, don't use 'Add Comment' when you edit your own submission..use 'Edit Submission') ------------------------------------------------------------------------ [2002-12-04 11:36:49] sroussey@network54.com Yes, the problem occurs without the Zend addon. Zend Accelerator won't work with PHP 4.3 anyhow, so I turned it off. In the other message I proved myself to be a bad typist. :( I meant to say _without_ Zend Accelerator... ------------------------------------------------------------------------ [2002-12-04 00:38:50] derick@php.net Does the crash still occur when you disable Zend Accelerator? Derick ------------------------------------------------------------------------ [2002-12-03 20:41:29] sroussey@network54.com I tried with 4.3RC2. Bug still exists, crashing at least 13 times in the couple of minutes the server was able to run with Zend accelerator... I HATE this bug. Grr. I case I can take the time to do a walkthrough since it still exists... ------------------------------------------------------------------------ [2002-11-29 15:24:13] sniper@php.net 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 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
