Very long complicated script causes php to segfault, both as an Apache Module and from the command line.  Sorry I can't reproduce a short script that reproduces this or narrow it down for you.  I moved all the includes into the main file and it is 165K in length.  This script works fine in PHP 4.0.0.  Following is a gdb backtrace from the core file generated from the commnad line.  I can provide the code that generated this, but only to individual people, not the list (our product hasn't been released yet).  The problem moves around the script.  If you add HTML code to the top of the file the crashes moved that many characters closer to the beginning.  Thanks for creating an (otherwise) useful language!  Let me know if I can provide any more information.
