If I use the script below and push the
refreshbutton of my browser several times
Apache generate a segfault.
I think this is a problem with arrays in PHP.

<gdb> run -DSSL -X
Starting program: /usr/local/apache/bin/httpd -X -DSSL
(no debugging symbols found)
((now, I am pushing the refreshbutton in my netscape several times))
Program received signal SIGSEGV, Segmentation fault.
