#23196 [Opn->Fbk]: Strange Core Dumps

ID: 23196 Updated by: sniper@php.net Reported By: dave at socrates dot thinkhost dot com -Status: Open +Status: Feedback Bug Type: CGI related Operating System: FreeBSD-4.7RC PHP Version: 4.3.2RC1 New Comment: Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. Get the latest STABLE cvs snapshot first.

I've spent the afternoon trying everything I can think of, all signs point to this problem being specific to the 4.3.2RC1 source tree. I am going to wait for the next version of PHP that is not RC grade. Also note that I built a "minimal" PHP CGI (with a very limited set of configure commands, to rule out the extensions as the cause of the problem), and it dumped a core which revealed the same end result in the back trace as the one I have already posted. ------------------------------------------------------------------------ [2003-04-22 14:12:38] dave at socrates dot thinkhost dot com Okay, I CVSup'ed the FreeBSD source, and made a new world and kernel. I also download a fresh copy of the 4.3.2RC1 source. I noticed during the configure command output, that bison was missing, so I added bison from the ports, and re-build the php CGI binary. Same problem. We are a RackSpace customer, and the hardware seems fine. We built everything else in the system using the same build tools, but only the PHP CGI is broken. As I mentioned, it works from the shell, but has trouble when called by suexec. How do I fix this problem? I am running out of ideas... ------------------------------------------------------------------------ [2003-04-21 12:56:50] sniper@php.net Most likely just broken system (hardware or compile tools) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
