PHP 4.0 Bug #5025: Segmentation fault when using deeply nested scripts

From: mlemos@acm.org Operating system: Linux PHP version: 4.0 Latest CVS (14/06/2000) PHP Bug Type: Reproduceable crash Bug description: Segmentation fault when using deeply nested scripts When running a large multi-file script using PHP standalone CGI executable from the shell, it crashes with segmentation fault after running a long and deeply nested (but not recursive) script. This also happens with PHP 3. Running gdb with the latest PHP 4 version, there were 376 stack frames when the program crashed somewhere in Zend code. I thought it was a stack limit problem, but then I run ulimit -s unlimit and it still crashed in the same code. I also set the memory limit to a very high value but with no change. I have a 800KB strace output file if that helps, but all it is seen before the crash is a long sequence of brk() calls. If strace or gdb output helps just mail me back and I'll send the output to an address you want. Since I am stuck without being able to do anything to work around this crash, I am willing to open a telnet port so you can login in my machine when I am online, as my Internet link is not permanent. Just mail me or better, page me to ICQ UIN 15699174.
