Bug description: recursive call limitation

I dunno where to reply to that ... so I do it here :

> PHP 4.0 (Zend) uses the stack for intensive data, rather than using
> the heap. That means that its tolerance recursive functions
> is significantly lower than that of other languages.

> It's relatively easy to tell Zend not to use the stack for this
> data, and use the heap instead - which would greatly increase the

> may add a compile-time switch.

We definitly need a such flag.

Recursive functions are really usefull when you want to do some
mathematics or work with directory tree for instance.

By the way ... if there are a little stack ... I think we could have
problem with big script ... I could imagine a script who call a couple
of functions who have a lot of parameters !? It could be a problem !? No
!?

It's a bit scaring to have a such limitation !?

thank you if you could add that,

gregori
