Can you provide the full list of modules enabled (php -m), please? ------------------------------------------------------------------------ [2014-08-08 17:31:33] requinix@php.net What about with Xdebug disabled? ------------------------------------------------------------------------ [2014-08-08 17:28:24] atlantisnova at gmail dot com More info: my system is a virtualized debian 64 bit machine running on a Mac,,, the production server where we discovered the problem is an dedicated debian 64 box (php versions listed in original comment). Sorry for not posting the exact output before! Here's a modified script that shows the correct value of $b before the notice: class A{ function do_stuff(&$b) { var_dump('Before in function:', $b); $defined = 0; #trigger_error("If I fixed the undefined variable but enabled this line instead, it will also turn b from an object into a string! So user-triggered notices bork it as well."); $x = $undefined || $defined ? 14 : 0; var_dump('After in function:', $b); } } class B{} $a = new A(); $b = new B(); $a->do_stuff($b); var_dump('After function:', $b); --------------- output of above ------------------ string 'Before in function:' (length=19) object(B)[10] ( ! ) Notice: Undefined variable: undefined in /vagrant/src/temp.tmp.php on line 7 Call Stack # Time Memory Function Location 1 0.1017 4382640 {main}( ) ../temp.tmp.php:0 2 0.1018 4385776 A->do_stuff( ) ../temp.tmp.php:17 string 'After in function:' (length=18) string 'B' (length=1) string 'After function:' (length=15) string 'B' (length=1) ------------------------------------------------------------------------ [2014-08-08 17:22:55] atlantisnova at gmail dot com Yes it's exact and sure here's the output: ( ! ) Notice: Undefined variable: undefined in /vagrant/src/temp.tmp.php on line 6 Call Stack # Time Memory Function Location 1 0.0631 4382248 {main}( ) ../temp.tmp.php:0 2 0.0631 4385384 A->do_stuff( ) ../temp.tmp.php:16 string 'In function:' (length=12) string 'B' (length=1) string 'After function:' (length=15) string 'B' (length=1) ------------------------------------------------------------------------ [2014-08-08 17:18:15] requinix@php.net http://3v4l.org/VqsdQ Works for me. That's the exact repro script you used? And rather than some description of the actual result, how about posting the actual, actual result? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
