#49828 [Opn]: class-constant can't be set to negative infinity

ID: 49828 Updated by: Sjoerd@php.net Reported By: daniel dot meister at datahouse dot ch Status: Open Bug Type: Class/Object related Operating System: Ubuntu 09.04 PHP Version: 5.2.11 New Comment: Could reproduce with PHP 5.2-HEAD and PHP 5.3-HEAD. The error occurs on the line with: const a = -INF; Note that the same error occurs with: const a = -(1); Because you can't use an expression when defining a constant.
