Bug #16475 Updated: segfault at startup with Apache 2.0.35

ID: 16475 Updated by: sebastian.wolfgarten@gmx.net Reported By: sebastian.wolfgarten@gmx.net Status: Closed Bug Type: Apache2 related Operating System: Linux 2.4.x PHP Version: 4.2.0RC2-4 New Comment: Hi folks, great work :-) Apache 2.0.35 works now fine for me even with php4.3-dev (I took it from snaps.php.net). Again let me know when I should retry any other version of php... Thanks + bye, Sebastian Previous Comments: ------------------------------------------------------------------------ [2002-04-23 20:59:35] aaron@php.net This bug has been fixed in CVS. I just committed a fix for this in sapi/apache2filter/sapi_apache2.c version 1.74 (from CVS HEAD). If you are still seeing the problem after trying this version please reopen this bug. Thank you for using Apache/PHP! ------------------------------------------------------------------------ [2002-04-23 16:12:24] sebastian.wolfgarten@gmx.net Hi, try submitting a backtrace. See http://bugs.php.net/bugs-generating-backtrace.php to create it - it's quite simple but helps the developers a lot. Did you compile apache with the option "--with-apxs2"? Just gimme a hint when I should try to compile apache with php on my system again... Bye, Sebastian ------------------------------------------------------------------------ [2002-04-23 14:55:29] mclinden@informed.net Well, this is probably not much help, but with gcc-2.95.3, linux-2.4.18, apache 2.0.35 and PHP 4.2.0 I see the same behavior, namely, httpd -X crashes with a segmentation fault whenever I access ANY page on the server, PHP or not. This only happens AFTER the PHP module is loaded. With the vanilla apache (no php) I have no problems, whatsoever. Also, configuration of both apache and php is minimal. ------------------------------------------------------------------------ [2002-04-22 00:04:43] jwoolley@php.net AHA! I think I'm onto something. The DSO is segfaulting in the second initialization round when php_apache_server_startup(). That function calls php_apache_startup() which uses pthread_getspecific. It ends up looking up a structure which contains pointers that point to from the FIRST round, dereferences them, and poof, it dies. I'm working on a patch. ------------------------------------------------------------------------ [2002-04-21 18:48:21] jwoolley@php.net This appears to be heap corruption of some sort. I can reproduce the problem and am working on tracking it down. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
