#35159 [Bgs]: big variable value in recursive function crashes

ID: 35159 Updated by: nlopess@php.net Reported By: pekka at photography-on-the dot net Status: Bogus Bug Type: Scripting Engine problem Operating System: * PHP Version: 5CVS, 4.4.1 (2005-11-08) (cvs) Assigned To: dmitry New Comment: Currently you should avoid too deep recursion in PHP. We need (and Java also) to implement the Tail Call optimization, as can be seen in Lisp or Scheme. This allows to recurse without using the stack for some cases. This is one of the things I would like to do in the near future.

I would be very interested to learn if there is a workaround, when you need to recurse very large data sets? ------------------------------------------------------------------------ [2005-11-09 11:12:16] iliaa@php.net Thank you for taking the time to write to us, but this is not a bug.
