bug 49348 - notice on $this->undefined++

Hi! I've created a pull to fix bug 49348 - when undefined properties do not produce a notice when doing something like $this->undefined++, unlike regular variables that do. Unfortunately, this fix seems to require changing signature of get_property_ptr_ptr(), adding fetch type, which makes it impossible for 5.4, and which would require any module that is compiled for 5.5 add ifdefs if they override this handler (of course, I've fixed the ones in the core). The pull is at: https://github.com/php/php-src/pull/281 However, I think that even though missing notice is not that big a deal, having properties behaving inconsistently is, so this needs to be fixed. Anybody has any objection or sees something wrong with the patch? Also, if somebody has an idea of a better fix that won't require changing the API, it's be nice, I couldn't think of any. -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227
