We encouter include() -problems on a large project. It 
makes extensive use of classes and due to the fact that 
session-vars need to have the class-definitions before 
they can be used, some includes are circular. Of course 
all include-files are encapsulated into if(defined("C") 
{.. } blocks.

The included files before each weppage have a linecount at 
a maximum of 6214.

The errors result in classes not known and thus 
declaration of classes extended by them fail. Also 
function-declarations sometimes are missing. When using a

while(!function_exists("f"))
{ include("f.php"); }

this results in timeouts because of endless loops. Of 
course _should_ happen, because the constants mentioned 
above are all correctly set.

The errors occur not fully predictabel, and normally 
disappear when reloading the webpage. 

In the apache-error-log appaer the following lines, 
although I'm not sure if they are related to the problem:

[Fri Jul 20 16:01:34 2001] [alert] (14)Bad address: 
FastCGI: openf() of fcgi_dynamic_mbox "(null)" failed
[Fri Jul 20 16:01:52 2001] [notice] child pid 13112 exit 
signal Segmentation fault (11)

Any suggestions? Or is this project just too large for 
PHP4?
