Edit report at https://bugs.php.net/bug.php?id=68137&edit=1 ID: 68137 Comment by: leandro at leandro dot org Reported by: leandro at leandro dot org Summary: recursive closure gives segfault evaluating zero Status: Not a bug Type: Bug Package: Arrays related Operating System: Fedora 19 PHP Version: 5.5.17 Block user comment: N Private report: N New Comment: yes, my fault. i'm very sorry. but perhaps it would be nice if i got a gentle message like "can't reach infinite" instead of a bare segfault, isn't it? Previous Comments: ------------------------------------------------------------------------ [2014-10-02 20:51:16] requinix@php.net Segfault with it... commented? Of course. You created infinite recursion. ------------------------------------------------------------------------ [2014-10-02 20:39:40] leandro at leandro dot org Description: ------------ i don't know what is happening but i guess it can't eveluate (0 - 1) + (0 - 2) by some unknown reason when $n == 0 Test script: --------------- $wop = function($n) use ( &$wop ){ //if ($n == 0) return 1; //with this line commented, we get a segfault return $wop($n - 1) + $wop($n - 2); }; print_r( array_map($wop, range(0,20)) ); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=68137&edit=1
