ID: 37197 Updated by: [EMAIL PROTECTED] Reported By: ivoras at gmail dot com -Status: Open +Status: Feedback Bug Type: Reproducible crash Operating System: FreeBSD 6.1 PHP Version: 5.1.2 New Comment:
Yes, I do have a reason. You don't have to touch the production PHP and Apache - you can always install it into different location and listening on another port. Previous Comments: ------------------------------------------------------------------------ [2006-04-25 12:38:28] ivoras at gmail dot com Do you have a reason to believe this will help me - are there any changes in the session serializing code between the two versions? (This is a production machine and I can't risk downtime when I try the snapshot). ------------------------------------------------------------------------ [2006-04-25 12:09:11] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php5.1-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.1-win32-latest.zip ------------------------------------------------------------------------ [2006-04-25 12:07:36] ivoras at gmail dot com Description: ------------ PHP module in apache randomly crashes. Tried building debug version of PHP, but it doesn't change anything (there is no significant additional data in apache error logs). Attached is the result of Apache modules mod_whatkilledus and mod_backtrace. The problem seems to be this: "httpd in malloc(): error: recursive call" Talking to FreeBSD developers, this most likely happens if an application tries to use malloc() from a signal handler, while another malloc() is in progress, which apparently is allowed by GNU malloc() but not by BSD malloc(). Reproduce code: --------------- Cannot pinpoint crash location - possibly random or before/after PHP code starts to execute. Expected result: ---------------- Normal operation.
