I couldn't find a matching Bug-Report. If it wasn't caught by a test, maybe one should be added? not sure how tests work in PHP though. ------------------------------------------------------------------------ [2016-08-08 09:56:04] cmb@php.net So this is not a bug. :-) ------------------------------------------------------------------------ [2016-08-08 07:36:34] lars dot schultz at toolpark dot com sorry, had no opportunity to test it on other versions...or rather: did not know that I had the opportunity to test it on other versions.
