After all I said, it can be improved, for example, in zend_execute.c you can change on line 860+ the do_alloca and free_alloca macro's to use emalloc and efree. However, it'll slow things down a bit.

I have nothing to add about the technical aspects - but I just want to stress that the limit you're talking about, of one million nesting levels, is completely ridiculous. Generally, if you have a script that calls ANY function one million times, whether it's recursive or not, you shouldn't be using a scripting language. Moreover, recursive algorithms are almost inefficient to implement in structured languages, and you should never ever reach a depth of that magnitude. As a rule of the thumb, if you reached a depth level of more than a few thousand functions (which should be also very very very rare) - it's time to go back to the drawing board, since you're doing something wrong.
