#23196 [Opn]: Strange Core Dumps

ID: 23196 User updated by: dave at socrates dot thinkhost dot com Reported By: dave at socrates dot thinkhost dot com Status: Open Bug Type: CGI related Operating System: FreeBSD-4.7RC PHP Version: 4.3.2RC1 New Comment: My solution to the problem for the time being is to re-compile using the 4.3.1 source, which built a working PHP CGI binary (There goes your theory about hardware/compiler problems?). 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. Previous Comments: ------------------------------------------------------------------------ [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) ------------------------------------------------------------------------ [2003-04-14 01:53:23] dave at socrates dot thinkhost dot com I built a new PHP DSO and CGI for one of our FreeBSD machines. The odd thing is that the "same" (built with the same configure command) CGI binary works on a similar machine without error. The PHP CGI works fine when called from the shell, but dies and dumps a core when called by suexec (apache). A back trace of the core dump is included below: ================================================ Core was generated by `php'. Program terminated with signal 11, Segmentation fault.
