that should be "You make too many assumptions" and no that is not the case,
I was trying to point out that the number you showed us were arbitrary and
completely nonindicative (of anything).

then you have a php binary built with customized source code I
presume.

yes and display_errors is OFF - look in your php error log.

you implied that there was a limit when you said 'it just stops',
'it just stops' is not the same thing as a segmentation fault occuring.
or did you mean something like 'it just stops when you concentrate really hard
on your computer', or maybe you're implying that php has just aquired
self-awareness and is arbitrarily deciding when to put a stop to your recursion?
