Previous Comments: ------------------------------------------------------------------------ [2005-11-09 08:24:56] dmitry@php.net Crash occurs becaose of program stack overflow. All PHP versions are affected. ------------------------------------------------------------------------ [2005-11-08 21:21:22] support at zend dot com 4.3.11, 4.4.0 also affected, but with different limits... ------------------------------------------------------------------------ [2005-11-08 21:06:57] pekka at photography-on-the dot net correction: 5.0.4 is not free of this, in php 5.0.4 the limit is 1291 on same machine. ------------------------------------------------------------------------ [2005-11-08 20:27:05] sniper@php.net I can reproduce this with latest CVS of 5.1, using 35701 as the limit.
