When running a large multi-file script (it should run for several hours, or maybe even more) using PHP standalone CGI executable from the shell, it crashes with Segmentation Fault after running a wide and none-deep (max 5-10 level depth) recursive script.

I'm thinking it's a stack limitation problem.

I found this problem (which is very similar to the "recursive call limitation" (#1901) PHP Bug Report) with two my own Linux servers (PHP 4.0.4 and 4.1.0).

In the answer to those bug report you mentioned that you may add some compile-time switch, which will make PHP use heap, but not stack for intensive data.

Please let me know if such switch has been added and how I can use it with my servers or if you know some other way, which will help me to solve this problem.

Thanks in advance!

Please read instruction for submitting bugs.
You should attach backtrace ;)

Unfortunatelly we could not get the core file as we don't have the root access to the server. Also script crashes after it works for about 5 or even more hours. We run script in the new process, then, after several hours, we can see this process running, then, suddenly, it disappears.

Pls. let us know if you have implemented the switch we were asking about, as we really hope it will help us - we will contact server admins and will ask them to recompile the php with your switch.

I think you are using dev/test system, right?
Try it under test system. Unless you provide more details, it just can't be fixed :)
