Diagnosing a segfault error
I've set up a web server on a RootBSD VPS with Lighttpd and PHP via FastCGI to operate a site with the Drupal CMS. When I take a certain, repeatable series of steps in Drupal, I'm causing the PHP process to exit on signal 11, a segmentation fault.
I've already spent several hours over the past couple of weeks diagnosing this through trial and error, but haven't been able to figure out what's causing this or how to work around it. Even more flummoxing is that my company also has a RootBSD VPS account which is not having this problem. Their account is a step above mine and has a larger memory allocation, so I suspect that might be the problem or at least part of it, but I'm not sure.
I guess what I'm asking is, is there a way to get more information on what is causing such an error, or perhaps even where in Drupal's codebase it's occurring?
