Constant expessions have to be evaluated in context of defining class). Previous Comments: ------------------------------------------------------------------------ [2013-12-10 08:55:05] laruence@php.net thanks for spotting this and explained the reason. ------------------------------------------------------------------------ [2013-12-10 02:00:38] Terry at ellisons dot org dot uk Description: ------------ zval_update_constant_ex() evaluates a constant within the scope a class when executed within a class scope. The new code to support ASTs does not pass this context into the AST evaluator so the class context is lost and references to self::SOME_CONSTANT and parent::SOME_CONSTANT error.
